JR46572: Snapshot installation fails due to an error computing changes for the BPEL process install.

APAR status

• Closed as program error.

Error description

• The runtime compare/merge session does not contain all
  contributions found in tooling.
  
   In a C/M session, the 'element' attribute of every WSDL and XSD
  EMF object must be set to null.  The model operator for each of
  these models, as well as the feature filters, tell the C/M
  session to skip the comparison and copying of the element
  attribute.  The WSDL and XSD models will generate an updated DOM
  model when they are saved.
  
  In this particular scenario, since the BOModelOperator is not
  present, the C/M session will add the element object from the
  source XSDModelGroup EObject into its copy.  Since this is not
  null, when the compositor attribute is copied, the
  org.eclipse.xsd.impl.XSDModelGroupImpl.changeAttribute(EAttribut
  e) method will try to set  the new value since the element is
  not null.  This leads to the NPE.
  
  Adding the BOModelOperator functionality to the runtime should
  avoid the problem and also allow the C/M session to operate as
  expected.  I would also suggest ensuring the feature filters are
  in place as comparing models with their DOM representation in
  memory could lead to unexpected results.
  
  
  JR47718 is also required to resolve issues related to this
  problem.

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
  when the new version of the process application contains new
  artifacts like new XML schemas.
  
  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.
