I've run Oracle JRE and OpenJDK with it and both work OK; also some BlackBerry SDK tools built for Linux. I'm sure there's some rough edges, and I don't know about performance, but once I mounted the appropriate filesystems, things were working, and that was good enough for me. I think that you do have to pick between a current release of FreeBSD and 64-bit Linux binaries or an older release of FreeBSD and 32-bit Linux binaries, and no way to support both sizes on the same host; but that might be me misremembering.
