Description of problem: It is currently possible for JACC implementation classes to be specified as system properties, however it is not possible to specify the module to use when loading the classes. This BZ is to correct this situation so a separate system property can also be set to control the module.
Verified in EAP 6.4.5.CP.CR1. Module for loading JACC policy can be specified through org.jboss.as.security.jacc-module system property.
Retroactively bulk-closing issues from released EAP 6.4 cumulative patches.
