I have these crashes as well. The error report always differs a little bit. I found that the reason why azureus keeps crashing, seems to be the log files in ~/.azureus/logs/ when I delete those azureus starts up again without crashing right again.
For example azureus logs in logs/alerts_1.log that I'm having NAT issues and it needs an open UDP port etc. I'm not sure if switching from sun-jdk to gcj makes azureus not choke on these log files.
