  The infinite loop is caused by
  AbstractXMLSerializer.deserializeArray() is not compatible with
  the previous Axis based stack which uses a qualified namespace.
  

Local fix

• Create a new process in Process Designer 8.0.1 instead of
  importing the WLE 7.2 twx file into BPM 8.0.1.

  ****************************************************************
  The issue is caused by the XML parser used in web service
  integration. The parser incorrectly sents the array parent
  element as the child element. This in effect causes the
  parsing elements of array type go into a loop.
  

Problem conclusion

• This iFix corrects the XML parser by passing the correct
  children elements and thus correctly deserializing the array
  element.
  
  Install/Dependency information is available in the readme.txt
  on FixCentral. When the user goes to the download files page
  in FixCentral, the readme will be available with the fix
  package as a separate download.
