• Closed as program error.

Error description

• When using a Reference bound into JNDI to lookup a JNDI object
  in a foreign context, problems related to
  GatewayBundleContextProxy may occur.  Such problems are
  likely to be ClassCastExceptions or ClassNotFoundExceptions
  originating in a third party context factory.  APAR PM75089 may
  already be applied.

  ****************************************************************
  The GatewayBundleContextProxy class is augmented to the
  Context environment only if the context factory is IBM's after
  PM75089.  However, in the JNDI Reference case, the factory is
  IBM's initially but during the following indirect lookup it
  may be a non-IBM factory.  The environment is already
  augmented with GatewayBundleContextProxy which may cause third
  party factories problems.
  

Problem conclusion

• This APAR ensures that not only is the environment not
  augmented for non-IBM factories, but any augmentation added
  previously is removed if the factory is not IBM's.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.6 and 8.5.0.2.  Please refer to the Recommended
