Problem running Java Swarm on FreeBSD

[Horance Chou]

I've install Swarm 2.1.1 on my FreeBSD box (with some patch),
But, when i try to running jHeatbug, I got error messages:

#  javaswarm StartHeatbugs -b
/usr/local/lib/libjavaswarm.so: Undefined symbol "_activity_current"
(libjavaswarm.so)
Exception caught: no javaswarm in shared library path
java.lang.UnsatisfiedLinkError: initSwarm
        at StartHeatbugs.main(StartHeatbugs.java:15)

I've compared symbols of libjavaswarm on FreeBSD and libkaffeswarm on
Redhat Linux,
Nothing different beside the "GLIBC 2.1" related symbols.
(complete diffs are attached)

The Obj-C version applications an running perfectly on my BSD box.
I think that mean it's some kind of bug related to shared library
linking of FreeBSD,
which I can't do anything with it.

I noticed that libkaffeswarm.dll on Windows platform contains all
symbols of other libraries.
Maybe it's an "workaround" for the linking problem?
Please help me to build a shared library with all swarm symbols !
