In previous versions of JBoss EAP, it was found that an application's TCCL (thread context class loader) was not appropriately set when initializing MBeans found in .sar files. This meant that resources in the deployment were not available to the MBean upon initialization. In this update to the product, the TCCL is now set appropriately surrounding the call to the MBean initialization and MBeans can now access deployment resources upon initialization.
org.jboss.as.service.ParsedServiceDeploymentProcessor#newInstance should set the TCCL before creating the MBean instance.
Verified in 6.3.0.DR1.
