IT39913: NULL POINTER EXCEPTION DURING SAP ITERATIVE DISCOVERY

APAR status

• Closed as program error.

Error description

• On some versions of IBM Integration Bus version 10 the WMB
  interceptor classes are not available to the SAP connector code.
  This can cause Iterative Discovery to fail with a
  NullPointerException.
  
  Examining the iterative discovery logs shows the following root
  cause:
  
  ava.lang.NullPointerException

Problem conclusion

• The product has been updated so that failure to load the
  interceptor runtime classes does not cause a failure when using
  the Toolkit to perform iterative discovery.
