There is a JVM that is part of GCC called libgcj. It differs from Sun's JVM in that is uses "ahead of time compilation" of the Java code all the way to machine code. Whereas Sun's JVM runs on "java bytecode" and at runtime compiles this bytecode to machine code "just in time".
Unfortunately the build system for libgcj is abysmal and shameful, and the garbage collector will pause the process that runs it about 55 msecs every so often. So aside from the build system and the GC, libgcj is excellent work. I would start with libgcj. http://gcc.gnu.org/java/ It should be your path of best investment. Been there, done that.
