Null Pointer Exception when Building a SAP BPM DC

Hi All,

  I am giving a simple condition in exclusive choice gateway and when building the DC , it is giving the following Error :

  [BpemTask] BC-BMT-BPM-SRV com.sap.tc.glx.BpemTask execute() - Metamodel version validation...

Caused by:

java.lang.NullPointerException

at com.sap.tc.glx.BpemTask.metaModelVersionCheck(BpemTask.java:549)

anyone have the idea about this?

Thanks
Rohit
