Error description

  • Error Message: When using JVM application trace via the
    com.ibm.jvm.Trace API and printing it to the console with
    -Xtrace:print the application in the output name has one or more
    junk characters appended to the end.
    .
    Stack Trace:
    .
    The application name registered with trace was 16 characters or
    longer.
    

Local fix

  • The trace points can be written to a trace file and formatted
    offline instead of printed out directly. Alternatively the
    length of the application name registered can be shortened.
    

Problem summary

  • The problem is caused when the application name is longer than
    the size of the space intended for displaying it in the
    formatted trace point output of -Xtrace:print.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR3
    6.0.1 SR4
    .
    The JVM has been updated to correctly handle long application
    names when printing out trace points.
    

Temporary fix
