We did some profiling of or JBoss AS instance and noticed that audit logging on JavaEE resources is causing most of our allocations outside [TLAB] [1] s. This was a bit surprising to use since we don't have audit logging on. We tracked them down to `org.jboss.security.javaee.AbstractJavaEEHelper.authorizationAudit` which unnecessarily does an eager string conversion of every `org.jboss.security.authorization.Resource`. This could be done lazily on demand when audit logging is on in `AuditEvent#toString`. Since the map is already of type `Map<String,Object>` simply removing the call to `#toString()` fixes this. * don't do eager string conversion of resources in `AbstractJavaEEHelper#authorizationAudit` [1]: http://openjdk.java.net/groups/hotspot/docs/HotSpotGlossary.html#TLAB Issue: SECURITY-786 https://issues.jboss.org/browse/SECURITY-786
