A tiny Java agent to dump all classes loaded by the JVM (excluding arrays), made using the instrumentation API.
There are two "versions" of this project: one is the normal one (can be compiled with Java 7+, uses NIO), and the other one, which is compatible with all Java versions 5 and above.
To use, simply add -javaagent:path/to/classdump-version.jar as a JVM arg. (adding =debug at the end enables logging each class dumped)
Classes are dumped to _classdump, relative to the working directory.
This project builds like any normal Gradle project, just run ./gradlew build.
However, to compile the Java 5 version (./gradlew java5Jar), you will need to use Java 8 or below, as Java 9+ does not support compiling with compatibility for Java 5.
There are also GitHub Actions setup for this repo, allowing you to get a jar for every commit!
