Error description

• Unable to deploy multiple snapshots containing the same BPEL
  processes due to comparemerge errors.
  
  The first snapshot of a process app containing BPEL processes
  can be deployed. But when deploying further snapshots the BPEL
  install step fails during the compare merge functionality. This
  generally only affects BPELs which have interface WSDLs which
  make use of importing other XSD files.
  
  There are various errors that can occur which would be similar
  to these and would be seen on in the app cluster logs after the
  deployment:

  This is related to APARs JR44412 and JR46572. JR46572 is need
  with this to resolve the issues. This fix supercedes JR44412.
  

Local fix

Problem summary

• When activating a new version of a process application the
  differences between the different versions of the BPEL
  artifacts (as result of the multiple installed versions) are
  calculated. This calculation fails with the exception above.
  
  PROBLEM DETAILED DESCRIPTION:
  When creating multiple versions of a process application that
  contains BPEL based business processes, this can lead to an
  exception similar to this:

Problem conclusion

• With this interim fix installed the activation of multiple
  versions of the same process application should be possible
  without problems.
