Error description

  • Error Message: Character highlighting is not drawn correctly.
    .
    Stack Trace: N/A
    .
    The problem has shown up as incorrect graphical output, but this
    issue could be the cause of any problem where an invalid numeric
    value is being sent to a JNI routine via an 'int', 'short' or
    'byte' argument on LinuxPPC64 JVMs.
    

Local fix

  • The problem can be avoided by using the following Java command
    line argument:
    -Xjit:disableDirectToJNI
    Using this option may have a slight impact on the Java
    applications performance as this option will prevent the JIT
    from optimizing the JNI call out path.
    

Problem summary

  • The JIT failed to sign extend register passed arguments when
    calling JNI routines as is required by the LinuxPPC64 ABI.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR9
    5.0.0 SR12
    .
    The JIT was modified so that it will sign extend values when
    calling JNI routines on LinuxPPC64.
    .
    To obtain the fix:
    Install build 20100511 or later
    

Temporary fix
