The following should be added to run.conf to avoid deserialization bottleneck in arrays for JDK 1.6:
-Dsun.lang.ClassLoader.allowArraySyntax=true

This provides a workaround for issues in hibernate, remoting, and possibly other components.

This is the same as JBPAPP-907, except this issue is for EAP 5.

The fix for this issue will implement the workaround for JBPAPP-2277.
