Hi Aryeh,

ImageJ's compiler class (ij.plugin.Compiler) uses the undocumented,
deprecated sun.tools.javac.Main class to call the compiler, which I'm
guessing is not supported by JRockit, as the sun.tools.javac package
is not an official part of the Java specification. There is a new,
official Java compiler interface, javax.tools.JavaCompiler, that was
added in 1.6. It looks like JRockit works with 1.6 as of a few months
ago, so it would probably be possible to make ImageJ's Compiler use
javax.tools.JavaCompiler via reflection if available, and fall back to
the deprecated interface if not, resulting in a working "Compile and
Run" option with JRockit.
