IT47852: FOLLOWING APAR IT47319 THERE ARE STILL SOME SCENARIOS WHERE SCHEMAS CLASH

APAR status

• Closed as program error.

Error description

• Where an application includes multiple libraries which in turn
  contain schemas which have the same unqualified filename, but
  these schemas do not contain global elements with the same
  identifier then it is possible to erroneously receive the
  following error message:
  BIP4395E: Java exception: 'org.apache.xerces.xni.XNIException';
  thrown from class name:
  'com.ibm.broker.schemamgr.MbSchemaCompilerCL', method name:
  'error', file: 'MbSchemaCompilerCL.java', line: '587'
  This problem is similar to that reported in IT47319, however the
  fix for that APAR did not catch all possible occurences.
  

Local fix

• Rename the xsd in one of the libraries.

  This
  problem is similar to that reported in IT47319, however the fix
  for that APAR did not catch all possible occurences.
  

Problem conclusion

• Schemas of this form no longer produce an error message as long
  as there are no global elements that have name clashes.
