Byteman is a tool that allows runtime manipulation of Java bytecode through Java agents. It allows specifying Byteman rule scripts that can inject tracing, debugging, or testing code into methods at different points like method entry/exit. This provides a way to "muck around with the Java code to your heart's content" without needing the source code. Byteman rules can be used for tracing, profiling, or fault injection in integration tests. It also supports a JUnit runner and annotations to help with testing applications by simulating failures through rule scripts.

Byteman - Carving up your Java code
Chris Sinjakli

A tracing/debugging tool
Runtime manipulation of Java code

Java Agent API
Muck around with the bytecode to
your heart’s content

Java Agent API
package java.lang.instrument;
interface ClassFileTransformer
{
byte[] transform(ClassLoader loader, String
className, Class<?> classBeingRedefined,
ProtectionDomain protectionDomain,
byte[] classfileBuffer);
}

Who does this?
• About a million tutorials
– Usually print the class name
– At best adding simple trace code to methods
• Newer, cooler mocking frameworks
– Powermock, Mockito, JMockit
– Better approach then JMock & friends (which use
Proxy + CGLIB)
– Mock final classes/methods, plus other stuff
• Pure Java profilers?

Not that convenient
Who wants to spend their time
dealing with bytecode?

Byteman
Muck around with the Java code to
your heart’s content

How?
• Specify byteman.jar as a Java Agent when you
start your app
• Provide a Byteman rule script
• Can provide these scripts later (to a running
app) – app must be started with Byteman
listener

Simple program
package org.my
class AppMain
{
public static void main(String[] args)
{
for (int i = 0; i < args.length; i++) {
System.out.println(args[i]);
}
}
}

Run it
> java org.my.AppMain foo bar baz
foo
bar
baz
>

Byteman rule script
RULE trace main entry
CLASS AppMain
METHOD main
AT ENTRY
IF true
DO traceln("entering main")
ENDRULE

Byteman rule script
RULE trace main exit
CLASS AppMain
METHOD main
AT EXIT
IF true
DO traceln("exiting main")
ENDRULE

Run it
> java -
javaagent:byteman.jar=script:appmain.btm org.m
y.AppMain foo bar baz
entering main
foo
bar
baz
exiting main
>

Worth mentioning
• You can use it on classes you don’t have the
source for
• You can even use this on core Java classes
(java.lang) – Byteman makes you confirm
• Works on interfaces too (all implementing classes
get your injected code)
• Much more sophisticated rule scripts
– Different “AT” points in method
– “IF” statements that do something
– Access to local variables (eg “AFTER WRITE $foo”)

Testing support
• Comes with a JUnit Runner
• Define the rules (from earlier scripts) as test
annotations
• Useful for fault injection (integration tests
where you’re not mocking everything out?)

$Testing support @Test @BMRule(name=“foo”, targetClass = “FileInputStream”, targetMethod=“<init>(File)”, condition=“$1.getName().equals(“doesnt_exist.txt”)”, action=“throw new FileNotFoundException(“It’s not there!”)”) public void testReadFile() { ... myClass.processFile(“doesnt_exist.txt”); // Throws an exception ... }$

Testing support
• Rule in previous example will only be in place
for that test
– Can annotate class instead to apply to all tests
• There’s also @BMScript to import external
rule scripts
• Relatively simple to run with maven (config
samples on website)

Summary
• Seems cool
• Not sure what I’d actually use it for
• Integration tests most likely candidate

This document provides examples of using Byteman to intercept method calls and get additional information during application deployment. It demonstrates getting the hash code when deploying an application by intercepting the addContent method and outputting the repoRoot and messageDigest parameters. It also shows an example of intercepting the getContentInputStream method using an AFTER WRITE rule to output the input stream after it is set. Finally, it mentions the ability to intercept exceptions using AT CATCH rules.

Log4j Logging MechanismKunal Dabir

SLF4J Explained........Sunitha Satyadas

SLF4J is a logging facade that provides a simple API for various logging frameworks. It allows developers to use a simple logging API while enabling switching between logging implementations. SLF4J acts as a facade for other logging frameworks like Log4j and java.util.logging. It provides parameterized logging methods and markers to tag log messages. Logback is a popular logging implementation that can be used with SLF4J.

Test all the things! Automated testing with Drupal 8Sam Becker

With Drupal 8 released, one of the most important aspects of building a website or module has changed dramatically for the better. Developers now have a myriad of tools at their disposal to be able to test their code. If you are interested in improving your code and preventing bugs, but are unfamiliar with acronyms like BTB, KTB and WTB, this session is for you. If you’ve dabbled in testing but haven’t explored the depths of PHPUnit or Mink, then this session is for you.

SLF4J (Simple Logging Facade for Java)Guo Albert

SLF4J is a simple logging facade that allows switching between different logging frameworks at deployment time without code changes. It provides a common interface for logging and allows migrating from one logging framework like log4j to another like JDK logging easily by changing a jar file. Popular frameworks like Logback, Log4j, and JDK logging have SLF4J bindings. Using SLF4J avoids vendor lock-in and allows plugging in the desired logging framework.

Typescript FundamentalsSunny Sharma

- TypeScript is a typed superset of JavaScript that adds types, interfaces, and classes but compiles to plain JavaScript. It allows for early detection of bugs through compile-time type checking. - Some key features of TypeScript include type annotations, access modifiers, interfaces, inheritance, enums, modules, namespaces, and generics. It supports common data types like boolean, string, number, arrays, and functions. - TypeScript works by compiling TS files to JS files and optional sourcemaps that allow debugging the original TS code. It uses the Node.js runtime and supports editors like VS Code through plugins. Modules are preferred over namespaces for organizing code in larger projects.

Ruby, the language of devopsRob Kinyon

This document discusses why Ruby is a good programming language for operations staff. It notes that operations involves tasks like building servers, packaging, monitoring, and provisioning that can be programmed. While shell scripts and Perl are commonly used today, Ruby has advantages like allowing multiple versions of the same library, being beginner friendly due to tutorials and syntax, and its use of blocks for iteration, cleanup and separating concerns. Ruby also has good tooling for devops tasks like configuration management, logging and packaging that operations staff can benefit from due to the ability to write plugins for these tools.

Variables in Pharo5Marcus Denker

This document discusses new developments in variable representation in Pharo5. It notes that everything used to be represented as objects, including variables, but variables were represented via associations. In Pharo5, variables are now represented as subclasses of objects called slots and literals. This allows variables to be annotated and have custom behavior via delegation to their metaobjects during code generation. It provides examples of using simple slots, weak slots, and property slots, and outlines the roadmap for further developing the slot system in Pharo6.

SLF4J+LogbackGuo Albert

Logback is an evolution of Log4j that implements the Simple Logging Facade for Java (SLF4J) API. SLF4J acts as an abstraction layer for logging frameworks like Log4j, Logback, and Java Util Logging, allowing the user to switch frameworks at deployment time. Logback offers a native implementation of SLF4J and exposes its logging API through SLF4J, so when using Logback you are actually using SLF4J. The presentation provides an example Logback configuration file and references for further information.

Frankenstein is a tool for testing Swing applications that allows recording and playing back user interactions. It was created to address limitations of other testing tools in supporting multithreaded applications and custom UI components. Frankenstein works by hooking into the Swing event queue to record events during recording and then replay them during playback. It uses a Ruby driver to write modular, parameterized tests and provides features like synchronization of multithreaded tests and customizable reporting.

Flowzupzup.org

Flow is a static type checker for JavaScript that tracks types as they flow through a program to find errors. It works by parsing code, generating an abstract syntax tree, performing type inference to create a Flow graph, then evaluating the graph to find errors. Basic setup involves installing Flow, adding "// @flow" comments, and running the "flow" command to check files. Flow is focused on soundness while TypeScript prioritizes tooling and scalability.

Oredev 2015 - Taming Java AgentsAnton Arhipov

Java agents are pluggable self contained components that run embedded in a JVM and intercept the classloading process. They were introduced in Java 5 along with the powerful java.lang.instrument package. Java agents can be loaded statically at startup or dynamically (programmatically) at runtime to attach to a running process. Java agents were an awesome addition to the JVM as it opened a lot of opportunities for tool designers and changed Java tooling landscape quite drastically. In conjunction with Java bytecode manipulation libraries it is now possible to do amazing things to Java classes: we can experiment with programming models, redefine classes at runtime, record execution flow, etc. I’d like to give an overview of Java agents’ functionality along with the usage examples and real world experiences. You will learn, how to implement an agent and apply Instrumentation API in combination with bytecode manipulation libraries to solve interesting tasks.

Byteman and The Jokre, Sanne Grinovero (JBoss by RedHat)OpenBlend society

This document provides an introduction to Byteman and The Jokre. Byteman is a scriptable Java agent that allows testing code behavior at runtime without changing sources by simulating unexpected events.

Will it blend? Java agents and OSGiRobert Munteanu

Java agents are a little-known but extremely powerful part of the Java ecosystem. Agents are able to transform existing classes at runtime, allowing scenarios such as logging and monitoring, hot reload or gathering code coverage. However, their usage presents a number of pitfalls as well. In this talk we will present the steps of writing a java agent from scratch, indicate various common mistakes and pain points and draw conclusions on best practices. Special care will be taken to discuss how running in an OSGi environment affects Java agents and how we can best approach integration testing in a modular environment. After this talk participants will have a better understanding of the Java instrumentation API, how it fits in with OSGi runtimes and about should / should not be done with it.

DigitalMara analyzed these announcements: • AI enhancements for Windows 11 By embedding AI capabilities directly into the OS, Microsoft is lowering the barrier for users to benefit from intelligent automation without requiring third-party tools. It's a practical step toward improving user experience, such as streamlining workflows and enhancing productivity. However, attention should be paid to data privacy, user control, and transparency of AI behavior. The implementation policy should be clear and ethical. • GitHub Copilot coding agent The introduction of coding agents is a meaningful step in everyday AI assistance. However, it still brings challenges. Some people compare agents with junior developers. They noted that while the agent can handle certain tasks, it often requires supervision and can introduce new issues. This innovation holds both potential and limitations. Balancing automation with human oversight is crucial to ensure quality and reliability. • Introduction of Natural Language Web NLWeb is a significant step toward a more natural and intuitive web experience. It can help users access content more easily and reduce reliance on traditional navigation. The open-source foundation provides developers with the flexibility to implement AI-driven interactions without rebuilding their existing platforms. NLWeb is a promising level of web interaction that complements, rather than replaces, well-designed UI. • Introduction of Model Context Protocol MCP provides a standardized method for connecting AI models with diverse tools and data sources. This approach simplifies the development of AI-driven applications, enhancing efficiency and scalability. Its open-source nature encourages broader adoption and collaboration within the developer community. Nevertheless, MCP can face challenges in compatibility across vendors and security in context sharing. Clear guidelines are crucial. • Windows Subsystem for Linux is open-sourced It's a positive step toward greater transparency and collaboration in the developer ecosystem. The community can now contribute to its evolution, helping identify issues and expand functionality faster. However, open-source software in a core system also introduces concerns around security, code quality management, and long-term maintenance. Microsoft’s continued involvement will be key to ensuring WSL remains stable and secure. • Azure AI Foundry platform hosts Grok 3 AI models Adding new models is a valuable expansion of AI development resources available at Azure. This provides developers with more flexibility in choosing language models that suit a range of application sizes and needs. Hosting on Azure makes access and integration easier when using Microsoft infrastructure.

Microsoft Build 2025 takeaways in one presentationDigitalmara

Byteman - Carving up your Java code

1. Byteman - Carving up your Java code Chris Sinjakli

2. A tracing/debugging tool Runtime manipulation of Java code

3. Java Agent API Muck around with the bytecode to your heart’s content

4. Java Agent API package java.lang.instrument; interface ClassFileTransformer { byte[] transform(ClassLoader loader, String className, Class<?> classBeingRedefined, ProtectionDomain protectionDomain, byte[] classfileBuffer); }

5. Who does this? • About a million tutorials – Usually print the class name – At best adding simple trace code to methods • Newer, cooler mocking frameworks – Powermock, Mockito, JMockit – Better approach then JMock & friends (which use Proxy + CGLIB) – Mock final classes/methods, plus other stuff • Pure Java profilers?

6. Not that convenient Who wants to spend their time dealing with bytecode?

7. Byteman Muck around with the Java code to your heart’s content

8. How? • Specify byteman.jar as a Java Agent when you start your app • Provide a Byteman rule script • Can provide these scripts later (to a running app) – app must be started with Byteman listener

9. Simple program package org.my class AppMain { public static void main(String[] args) { for (int i = 0; i < args.length; i++) { System.out.println(args[i]); } } }

10. Run it > java org.my.AppMain foo bar baz foo bar baz >

11. Byteman rule script RULE trace main entry CLASS AppMain METHOD main AT ENTRY IF true DO traceln("entering main") ENDRULE

12. Byteman rule script RULE trace main exit CLASS AppMain METHOD main AT EXIT IF true DO traceln("exiting main") ENDRULE

13. Run it > java - javaagent:byteman.jar=script:appmain.btm org.m y.AppMain foo bar baz entering main foo bar baz exiting main >

14. Worth mentioning • You can use it on classes you don’t have the source for • You can even use this on core Java classes (java.lang) – Byteman makes you confirm • Works on interfaces too (all implementing classes get your injected code) • Much more sophisticated rule scripts – Different “AT” points in method – “IF” statements that do something – Access to local variables (eg “AFTER WRITE $foo”)

15. Testing

16. Testing support • Comes with a JUnit Runner • Define the rules (from earlier scripts) as test annotations • Useful for fault injection (integration tests where you’re not mocking everything out?)

17. Testing support @Test @BMRule(name=“foo”, targetClass = “FileInputStream”, targetMethod=“<init>(File)”, condition=“$1.getName().equals(“doesnt_exist.txt”)”, action=“throw new FileNotFoundException(“It’s not there!”)”) public void testReadFile() { ... myClass.processFile(“doesnt_exist.txt”); // Throws an exception ... }

18. Testing support • Rule in previous example will only be in place for that test – Can annotate class instead to apply to all tests • There’s also @BMScript to import external rule scripts • Relatively simple to run with maven (config samples on website)

19. Summary • Seems cool • Not sure what I’d actually use it for • Integration tests most likely candidate

20. Questions?

Editor's Notes

#6: Other stuff == you’re screwed if you aren’t doing DI
#19: Maven config needed to put byteman jar in classpath, and spin up a new JVM so that the one running the tests doesn’t get polluted
