Local fix

  • Disable the shared cache by passing "-Xshareclasses:none" java
    command line option.
    

Problem summary

  • Shared string table corruption caused an internal VM structure
    to have invalid address for its data member leading to crash in
    j9dyn24.dll
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR8
    .
    Additional checking has been added to the VM code  to ensure
    that the data members of internal VM structure are valid and
    aligned correctly.  If the string table is found to be corrupt,
    it will be re-created.
    .
    To obtain the fix:
    Install build 20100109 or later
