    only when the job is run by some users.

    defined, or have their home directory set to '/' (root) or ""
    (empty string) or some other invalid location.

Local fix

  • z/OS Users wishing to run Java applications typically require a
    writable home directory. One should be created to avoid this
    particular XML Resolver problem.
    

Problem summary

  • On z/OS it's possible for the value of user.dir to be ".", "/"
    or "". The XML catalog resolver in XML4J doesn't tolerate any of
    these values very well and will print the stack trace of an
    exception to System.err when the resulting URL cannot be read.
    Since the exception is printed to System.err customers (like
    this one) may see it in a log and be alarmed about it.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR10 FP1
    6.0.1 SR1 FP1
    7.0.0 SR1
    .
    IBM JVM has been updated to correctly handle
    java.net.UnknownHostException.
