FreeBSD 5.1, Tomcat 5.0.19, which JDK?

[Rowdy]

Greetings,

I hav been trying to get Tomcat to run on my FBSD 5.1-R system, but have 
been experiencing the infamous:

SIGBUS    10*  bus error
Full thread dump Classic VM (diablo-1.3.1-0, green threads):
...

A (partial) portversion output from my system (hopefully including all 
that is relevant) is:

diablo-jdk-1.3.1.0_1        =  up-to-date with port
jakarta-tomcat-5.0.19       =  up-to-date with port
javavmwrapper-1.4           =  up-to-date with port
jdk-1.4.2p6_4               =  up-to-date with port
linux-sun-jdk-1.4.2.04      =  up-to-date with port
linux_base-7.1_7            =  up-to-date with port

A quick Google revealed that the solution for nearly everyone else with 
the same error was to upgrade something (OS version, Tomcat, Diablo 
etc.), however everything here is up to date, the server is cvsuped 
regularly.

I wondered whether it was an issue with the Diablo JDK, but I couldn't 
find an easy way of changing it, especially when the path to diablo/bin 
appears to be hard-wired into tomcat50ctl.

I renamed the diablo directory and made a symlink from the jdk-1.4.2 
directory to the diablo-1.3.1 directory, and restarted tomcat.

To my surprise it started just fine.  I ran thru a few of the examples, 
left tomcat it running overnight, and the next morning (and, in fact, 
the morning after that too) it was still running.

So the question probably is: does Tomcat 5 really *need* the Diablo JDK 
or will it run fine with the other one?

Btw this is not a production server, just something for me to play with 
at home, so high-availbility is not required, but the less maintenance 
the better :)

Thanx

Dave
