diablo-java crashes firefox

[Rick Voland]

I recently installed the new binary diablo-java from the FreeBSD 
Foundation (Thanks much for all your hard work).  It installed fine, but 
it doesn't work properly yet.   Firefox about:plugins indicates that 
diablo-java has been registered.

When I go to www.java.com and choose "verify installation," Firefox 
crashes as soon as the webpage indicates "Trying test 1" with the error 
message:

INTERNAL ERROR on Browser End: Listen on server socket failed
System error?:: Invalid argument

----------------------------

Configuration:

FreeBSD 6.0-RELEASE-p6 with SMP kernel
2 x 233MMX Pentium, 256 MB RAM
/etc/make.conf contains CPUTYPE?=pentium-mmx
diablo-jre-freebsd6-1.5.0.06.00.tbz
xorg-libraries-6.9.0
javavmwrapper-2.0_6
firefox-1.5.0.2,1 recompiled and reinstalled after installing 

     diablo-java
[all software including operating system and kernel (except diablo-java) 
compiled on this computer through make, make install, make clean.]


-----------------

pkg_add gave a warning after installing diablo-java that versions for 
xorg-libraries and javavmwrapper were newer than expected.

------------------------

Another verification that diablo java installed properly:
$ /usr/local/bin/java -showversion
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build diablo-1.5.0-b00)
Java HotSpot(TM) Server VM (build diablo-1.5.0_06-b00, mixed mode)

Thanks for any suggestions.
