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
