PM68597: INVALID XML COULD CAUSE A RUNTIME CRASH IF THE RESTART FLAG IS USED IN THE INPUT TYPE TREE

APAR status

• Closed as program error.

Error description

• A map that watches for XML files under Launcher control could
  crash the Launcher, if it receives certain sequences of invalid
  XML data.  This only affects maps which use modified type trees,
  imported from the XML schemas, and then only when the RESTART
  attribute is added to avoid the whole XML file being marked as
  invalid.
  
  The same crash can be seen if a sequence of XMLs are processed
  in one transaction under an immediate runtime, such as the
  Design Studio.
  

Local fix

• WTXCQ - WTX00041033
  PB / PB
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender customers using Xerces type
  tree and restart attribute
  
  Problem Description:
  Out of memory condition caused by loop due processing of
  multiple run maps with XML input where Xerces type tree had
  restart logic on only some parts of tree.
  The abend shows stack trace similar to:
  SetUpLS
  PushLS
  BeginObject
  DstxXMLDocHandlerImpl::beginObject
  DstxXMLElement::buildDataObjects
  DstxXMLElement::buildDataObjects ? repeats many times
  
  
  Platforms Affected:
  ALL
  

Problem conclusion

• Corrected initialization of restart logic. Insure that initially
  XERCES tree set up to fail if XML error. (WTX needs to find
  element with restart attribute to turn off)
  
  Delivered in:
  8.3.0.5, 8.4.0.4
