Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You receive DFHAP0001 An abend (code 0C4/AKEA) has occurred
  at offset X'00000548' in module DFHAPLJ1.
  It was found that module DFHRZTA GET_DEBUG_DATA processing does
  not check for a zero pointer before moving in the data.
  The routine GET_DEBUG_DATA should return an exception to say
  that there is no debug data, but instead moves garbage into the
  debug block, resulting in an 0C4 when DFHAPLJ1 attempts to use
  the incorrect values.

  ****************************************************************
  A Web service provider is running in CICS and a task is attached
  using request streams. There is an active debug profile for this
  transaction. The task includes a link to a java application and,
  because debug is active, DFHAPLJ1 calls RZTA GET_DEBUG_DATA.
  The buffer supplied by DFHAPLJ1 is in uninitialized storage.
  There is no debug data but DFHRZTA returns an OK response.
  DFHAPLJ1 attempts to access the data which can cause an
  0C4 abend, depending on the values in the buffer.
  

Problem conclusion

• DFHRZTA has been changed to return an exception response, with
  reason no_debug_data, when there is no data to return for
  a RZTZ GET_DEBUG_DATA request.
