Facing NULL pointer exception in initializeValues (Axis2-kernel jar)

["Sharma, Sachin" <sh...@synygy.com>]

Hi, 
using axis2 jars for past one year in reports project, regarding interaction with microsoft reporting webservices. But without any change in axis2 jars, as well as without any upgrade in report-server following exception comes, when I try to view a report that doesn't exist on reportserver:
