Local fix

Problem summary

  • The exception occurs if the DTFJ ImageAddressSpace.getPointer()
    API is invoked when reading a zOS system dump containing a mix
    of 31-bit and 64-bit processes.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR5
    6.0.1 SR6
    .
    The DTFJ API implementation has been corrected so that the
    ImageAddressSpace.getPointer() API functions correctly for zOS
    system dumps.
