JavaC
From APIDesign
JavaC is the Java source to bytecode compiler. Thanks to TulachMoreDEW project, it can run in a browser. For years NetBeans editing capabilities were based on nb-javac - a manual fork of official OpenJDK javac codebase distributed under GPLwithClassPathException license. In 2021, it was decided the ApacheNetBeans project can distribute the nb-javac component as part of NetBeans binaries. The nb-javac component is an autogenerated backport of JavaC from the latest JDK that can run on JDK8. The same javac can then be used only any JDK. That has significantly simplified distribution, bundling, testing of the NetBeans IDE on various JDK versions.
