I get the following error trying to start JBoss-3.0.7 under jdk1.6.0_04:

I've seached this site and the wider internet for resolutions to this and there appear to be none. Can anybody tell me if there is a solution yet or do I have to use a later version of JBoss and, if so, which one?

We need to use an early version of JBoss for regression testing purposes.
