August 27, 2001: Greg Lewis has released a long-awaited port of the JDK 1.3.1 software. It can now be built from the ports directory ports/java/jdk13. It should be noted that all notes below apply and it is still very much a developer-only release and it is not recommended for use in production environment.

July 16, 2001: Greg Lewis releases patches for developers interested in building a native FreeBSD JDK 1.3.1. It should be noted that this is very much a developer only release and will not build a working JDK. The patches are primarily being released as an opportunity for interested people to be able to contribute to the porting effort without having to start from scratch. The patches and some cursory build instructions may be downloaded at http://www.eyesbeyond.com/freebsddom/java/jdk13.html

September 15, 2000: Andrew Gallatin and Sean O'Connell have been working on getting IBM's JDK 1.3 working. To make them work on your system, you will have to patch some of your FreeBSD sources. They have provided patches based on your version:
4.0-RELEASE
4.0-STABLE
-CURRENT (pre-SMPng)

To quote Drew's message:

I've finally gotten the IBM jdk 1.3 working. I haven't tested it very
heavily    AWT stuff seems to finally work though.

Here's an updated patchset to a pre-SMPng -current. The patchset
does the following:

- changes MINSIGSTKSZ from 8192  to 2048
- implements linux_rt_sendsig() & linux_rt_sigreturn()
- implements userland sigtramp code for linux_rt_sigreturn()
- implements linux_to_bsd_sigaltstack & bsd_to_linux_sigaltstack() to
        fix a bug in linux_sigaltstack & to avoid lots of cut-n-paste in
        linux_rt_sigreturn().  This also fixes the "Java HotSpot(TM)
        Client VM warning: cannot uninstall alt signal stack" one sees with
        Sun's 1.3 JDK.
- changes the MAP_STACK flag to MAP_ANON for  LINUX_MAP_GROWSDOWN
        mmaps.  This was the final step in getting it working.  Any VM gurus
        out there want to talk about this one?  There's apparently
        something wrong with autogrowing linux thread stacks[*]

Patches at: http://www.cs.duke.edu/~gallatin/linux_sa_siginfo/diff

[*]The "problem" is the heuristic used by vm_map_growstack() to
determine whether the stack part of the main process stack.  We
currently use:

        is_procstack = addr >= (vm_offset_t)vm->vm_maxsaddr;

where vm->vm_maxsaddr comes from exec_new_vmspace():
        vmspace->vm_maxsaddr = (char *)USRSTACK - MAXSSIZ; 

The IBM JDK's main thread reduces it's stack size to rlim_cur=2040*1024.
It then creates stacks for its threads at addresses which are greater
than vm_maxsaddr but less than the current bottom of the main process
stack as defined by p->p_rlimit[RLIMIT_STACK].rlim_cur. The first time
a thread accesses something requiring this region to grow, it goes
down in flames.

And Sean's email:

I did a Quick&Dirty MFC of Andrew Gallatin's work on getting the 
IBM Java SDK to work.  I was able to run the appletviewer on one
of the demos and it worked.  I cannot say much more than that.

The patches are all relative to /usr/src (or / since they are
all in sys )

The majority of the patches are for files in /sys/i386/linux.
You should be able to apply the patch; cd to /sys/modules/linux;
type make; kldunload linux; type make install; and kldload linux

There is an additional change which sets the MINSIGSTKSZ to 2048
in sys/sys/signal.h .. this will require a kernel rebuild to
take effect.

July 18, 2000: Ernst de Haan has done some work getting Sun's Linux JDK 1.3.0b9 to run on 4.0-STABLE. The .java_wrapper file can be found here. (Don't forget to rename it to .java_wrapper)

Ernst's email:

Just one more hint: Change the jre/lib/jvm.cfg and put the last line on
top. So you will get:

   -classic
   -hotspot
   -server

I _do_ get one warning, BTW, when running the Swing app:

   Warning: Cannot convert string "MetaCtrl<Key>Insert" to type VirtualBinding

January 29, 2000: Work has not begun on the JDK 1.3 port. It will not be until after our JDK 1.2 release is done that we will begin on JDK 1.3.
