Problem conclusion


    

  • The absence of dealing with an edge condition of a byte
array data structure within a helper class utilized for
dealing with data buffers, has the potential to result in an
ArrayIndexOutOfBoundsException. The issue was fixed by
ensuring that these edge conditions were handled in an
appropriate manner.

The fix for this APAR is currently targeted for inclusion in
fix packs 8.0.0.10 and 8.5.5.3.  Please refer to the
Recommended Updates page for delivery information:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
