We support *LINUX* threads in emulation mode with a GPL add-on package, but we don't have native kernel threads in a form usable by native FreeBSD software. (And I don't consider using the GPL code a requirement to use the JDK 'usable'.) Besides, using green threads almost always outperforms native threads on single processor boxes, even on server's with the existing green-threads implemention. (This has been my experience on both FreeBSD and Solaris, although I can't give you any benchmark numbers to prove it since my application is not a benchmark.) Also, it appears that getting kernel threads and a JIT working is difficult, as noted by the Linux JDK2 port. IMO, native threads is over-rated for most applications.
