Error description

• In IBM Rational Software Architect (RSA), during the validation
  in transaction 'commit()',
  'ContentTypeHelper.isSupportedResource()' and
  'isSupportedContent()' will be called in a thread stack where a
  NullPointerException results:
  
  [?BEGIN?]
  java.lang.NullPointerException

  com.ibm.xtools.modeler.ui.internal.utils.ContentTypeHelper.isSup
  portedContent(ContentTypeHelper.java:69)

  date(LiveValidator.java:95)
        at
  org.eclipse.emf.transaction.impl.AbstractTransactionalCommandSta
  ck.execute(AbstractTransactionalCommandStack.java:165)
  [?/END?]
  
  In the 'isSupportedResource()' method, there is a URI variable
  called 'fileURI' which is like ?pathmap://??, but not
  ?file://...?.
  
  As the program progresses, it gets a string variable called
  'filename'. The variable 'filename' is 'null' when the real URI
  is like ?pathmap://?? instead of ?file://...?.  As a result,
  this 'null' value for 'filename' will be transferred to
  'isSupportedContent()' and cause a 'NullPointException'.
  
  Once the 'NullPointException' occurs, the whole 'validate()'
  will fail and, ultimately, cause a transaction rollback.
