[ajug-members] Java crash with Tomcat

[Chris Fowler]

This may shed some light.

when we originally moved from 1.4 -> 6.06 on CentOS 5.1 our RMI code 
would experience the same crash.  Whenever we would start the RMI 
registry and the server it would immediately sigsegv.

Since we were planning to remove all RMI code anyway, I went ahead and 
rewrote the class in the application that called the RMI server and had 
it get the data needed another way.  The RMI server ran on the same 
server as the application so it was not really needed to begin with.

Even recompiling the RMI code did not solve our problem of crashing.  
This was crashing inside of a virtual machine.
