APAR status

  • Closed as program error.

Error description

  • Error Message: The error would most likely be a crash after we
    decompiled out from JITed code in the JVM somewhere
    .
    Stack Trace: N/A
    .
    

Local fix

Problem summary

  • Full Speed Debug (FSD) capability involves decompilation out
    from JITed code in order to effectively debug the Java program.
    The problem is we cannot decompile out from certain sections of
    JITed code (generated for a handful of special JCL methods)
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    6.0.1 SR5
    .
    The JIT compiler was fixed to avoid the special casing of the
    problematic JITed methods under debug mode.
    

Temporary fix
