Description:
============
Authentication API is not working in BW 5.11(TRA 5.8).
 
Environment:
===========
 
BW ALL
 
Symptoms:
========
In BW 5.11(TRA 5.8), following exception is thrown when domain level authentication is used.
com.tibco.ext.model.common.IORuntimeException: java.lang.NullPointerException

Caused by: com.tibco.pof.entity.EntityStoreException: java.lang.NullPointerException

The same works fine in BW 5.10( TRA 5.7).

Cause:
=====
This is caused by an invalid class path order. RV libraries are loaded in multiple places.

Resolution:
==========
Remove RV_HOME%/lib/tibrvnative.jar,%PSP%%RV_HOME%/lib/tibrvnativesd.jar  from  ibco.env.CUSTOM_EXT_PREPEND_CP  in the application tra file. They are already loaded from "%RV_HOME%/lib". You could make the same change in the Bwengine.tra file to apply towards the same in future deployments.
