APAR status

  • Closed as program error.

Error description

  • Error Message: During the startup of a large application, some
    expensive compilations may fail or an OutOfMemoryError signal
    may occur.  The footprint of large applications might increase
    due to more expensive and complex compilations being done by the
    JIT.
    .
    Stack Trace: N/A
    .
    

Local fix

Problem summary

  • The JIT collects information while the Java program is running
    to achieve better compilations.  This process is expensive and
    causes memory usage (footprint) to increase while running on
    large applications during their start up.  This is due to more
    complex methods being compiled.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR4
    .
    The JIT compiler has been updated to avoid collecting this
    information during the start up of large applications.
    To obtain the fix:
    Install build 20130108 or later.
