Apache Commons JCI
· Apache Commons JCI is a java compiler interface.
It can be used to compile Java itself, or any other language that can be compiled to Java classes (e.g. groovy or javascript).
It is well integrated with a FAM (FilesystemAlterationMonitor) that can be used with the JCI compiling/reloading classloader.
All the currently supported compilers feature in-memory compilation.
