Running Linux ELF binaries requires at least -stable, if not actually -current. The Linux emulation in the 2.1R is for Linux a.out binaries only. There is a JDK "port" for regular FreeBSD-current. It requires (I believe) Netscape b2 (the current version of Netscape is b4). I believe the JDK uses shared context variables across applets, which is a huge security hole. I don't know how the JDK can run in a fixed implementation, without changes. I suspect there will need to be a definition of an authenticated IPC mechanism some time soon for the bugfixed versions. Otherwise, run a non-bugfixed version (like b2), but don't go out on the net with it.
