Local fix

• RMIC compiler requires *all* the classes that get referenced
  indirectly from the bean classes (whether they are compiled or
  not),including the ones in the dependant .jars .So when running
  EJBDeploy
  customer has to ensure these extra classes are available in the
  classpath to EJBDeploy.
  

Problem summary

• IBM RMIC code does excessive classloading and resolution which
  helps improve performance at runtime but is unnecessary at rmic
  time.
  

Problem conclusion

• This defect will be fixed in:
  1.4.2 SR13 FP4
  1.4.2 SR13 FP4 (z/OS 64-bit)
  1.4.2 SR13 FP4 (Linux AMD64)
  1.4.2 SR13 FP4 (Windows AMD64)
  5.0.0 SR11 FP1
  .
  ibm orb code has been modified to prevent excessive class
  resolution during rmic time.
  .
  To obtain the fix:
  Install build 20100121 or later
  

Temporary fix
