Error description

  • Error Message: ClassNotFoundException incorrectly thrown from
    the ORB code.
    .
    Stack Trace: java.lang.ClassNotFoundException:
    a.b.c.d.UserClass at
    com.ibm.CORBA.iiop.UtilDelegateImpl.loadClass(UtilDelegateImpl.j
    ava:693)at javax.rmi.CORBA.Util.loadClass(Util.java:252)at

    com.ibm.rmi.iiop.CDRReader.read_value(CDRReader.java:2393)
    .
    Along with ClassNotFoundException, ClassCastException and
    ArrayStoreException may also be thrown due to incorrect
    ClassLoader being used.
    A valid ClassNotFoundException on an application thread,
    may lead to an incorrect ClassLoader to be used by the same
    application thread subsequently.
    

Local fix

Problem summary

  • The ORB was incorrectly throwing a ClassNotFoundException as an
    incorrect cached ClassLoader was being used.
    

Problem conclusion

  • The code has been modified to ensure that the stale classloader
    is not used to load a class.
