Error description

  • Error Message: On z/OS, function calls to get user name and
    password made through the JVM have a memory leak.  The memory
    leaks are typically on the order of tens of bytes each.
    .
    Stack Trace: N/A
    .
    To verify the memory leaks, the LE run-time option HEAPCHK can
    be used to determine the stacks responsible for the leaked
    string buffers.
        The call to j9sysinfo_get_username() will be in the stack
    traces.
    

Local fix

Problem summary

  • On z/OS, the method j9sysinfo_get_username() allocates temporary

    5.0.0 SR13
    6.0.0 SR10
