Java agent that allows to modify Minecraft client/server thread pool size

A small utility that allows you to grab/dump/take/get bytecode from a running Java Virtual Machine (JVM) and save it to disk.

Continuations / CoRoutines for Java 1.8 - Java 25. This library is an add-on to Tascalate Javaflow continuations library. It provides suspendable version of java.util.Stream, java.util.Iterator, java.util.function.* and helper classes to work with continuations.

Minimalistic declarative JVM instrumentation library on top of ASM

JIP — lightweight pure-Java profiler with bytecode instrumentation, self-contained HTML reports, and JFR companion

Capture HTTP request and response bodies as OpenTelemetry span attributes. Zero code changes. Works with Spring Boot 2 & 3, Tomcat, Jetty, Dropwizard.

Skip tests that don't matter. This Maven plugin uses bytecode instrumentation to track which tests cover which classes, then uses Git to run only the tests impacted by your changes.
