> FindBugs/SpotBug detects a couple of problems with the code base:
>  * Incorrect class casting - in XXServiceDef.equals
>  * Unnecessary NPE checks - for variables which is known to be non-null (for example,
because in other places a method is called on that object). In ServiceREST.java PublicAPIs.java,
ServiceUtil.java and independently in XUserMgr.java
>  * Collection.contains method call which is never true - in ServiceDBStore.validatePolicyItems
for policyItem.getAccesses().contains("") - because getAccesses doesn't store String objects
>  * Making public partially initialized objects in HadoopConfigHolder.initResourceMap()
>  * Calling toString on array, which is not too readable
