APAR status

  • Closed as program error.

Error description

  • Error Message: A segmentation error occurs during compilation
    when the JVM is in the start-up phase running in an emulated
    31bit zLinux OS.
    .
    Stack Trace: N/A
    .
    This only affects the JVM when running in an emulated 31 bit
    zLinux OS environment.
    

Local fix

  • This issue can only be worked around by disabling the JIT
    compiler with the -Xint option.
    

Problem summary

  • The problem is caused by the JIT compiler relying on the Linux
    uname command to determine if the hardware is 64bit.
    

Problem conclusion

  • The JVM only supports 64bit hardware therefore the query was
    invalid and the JIT compiler was modified to remove the query to
    prevent the segmentation error in this circumstance.
