Error description

  • Error Message: Although sizes for -Xscminaot and -Xscminjitdata

    the cache.
    .
    Stack Trace: N/A
    .
    

Local fix

Problem summary

  • Minimum space reserved for AOT and JIT data in shared class
    cache specified by -Xscminaot and -Xscminjitdata options
    respectively is not honored by JVM when both options are
    specified.
    In presence of both the options, JVM incorrectly calculates the
    free bytes available in shared class cache.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR3
    6.0.1 SR4
    .
    The JVM has been updated to correctly reserve the minimum space
    for AOT and JIT data by -Xscminaot and -Xscminjitdata options
    respectively, and to correctly calculate free bytes in the
    shared class cache.
