JBossAS 5.0.0 beta2 cannot start with JDK 6

I wanted to run some EJB3 applications on JBoss, and so I installed the most recent version of JBoss (JBossAS-5.0.0.Beta2). When starting the server with JDK 6 (build 1.6.0_02-b06), I immediately got ClassNotFoundException.

A search showed this JBoss bug JBAS-4491. As mentioned by one user in the report, one workaround is to use JDK 5. I don't like keeping multiple versions of JDK in my machine, and I have been running my other java applications with JDK 6 for some time. I will wait for JBossAS-5.0.0.Beta3.

Update on 10/24/2008 Friday: with more recent releases, e.g., jboss-5.0.0.CR2 & jboss-5.0.0.CR1, JBoss AS runs fine on JDK 6.
