The "JavaSoft reference" versions are green_thread based and that will
probably always be true for the 1.1 branch. The question is if HotSpot
(the new JVM due out soon after 1.2) will continue to support both. 

The Sun Production versions are all native thread based. I don't know if
they will work with green_threads.
