• Closed as program error.

Error description

  greater than 0x7F), an ArrayIndexOutOfBoundsException may be

  ****************************************************************
  When the IBM StAX parser reads a large XML document that is
  encoded in EBCDIC, an ArrayIndexOutOfBoundsException may be
  thrown if the XML document contains a character that is
  outside of the ASCII range (in other words, greater than 0x7F).
  

Problem conclusion

• The problem was resolved by introducing an additional array
  bounds check in the IBM StAX parser's EBCDIC decoder.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.15. Please refer to the Recommended Updates
