[jboss-user] [JBoss Portal] 64-Bit JVM in 2.6.4

Does anyone know the best 64-bit JVM and/or JAVA_OPTS that work well with JBoss Portal 2.6.4? I have been using "Java VM: Java HotSpot(TM) 64-Bit Server VM 1.5.0_13-b05,Sun Microsystems Inc." to no avail. I'm getting a few errors, such as the ones I listed in this thread earlier: http://lists.jboss.org/pipermail/jboss-user/2008-February/111071.html All of the deployments of JBoss that I'm about to install will be in the 64-bit environment, and I'm rather surprised that its not working "out of the box" like it always has when I would run it in a 32-bit environment. Thanks
