Local fix

  • N/A
    

Problem summary

  • The variable used internally was not able to handle zip file
    size more than 2GB (2^31). If the variable is modified to handle
    2^32 bit size, JDK can handle up to 4 GB. The 64-bit zip format
    is not supported in JDK 6 and considered as a permanent
    restriction.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR10
    6.0.1 SR2
    7.0.0 SR1
    
    The JVM is updated to handle zip file greater than 2GB but
    less than 4 GB. The 64-bit zip format is not supported for JDK 6
    and below releases. Upgrade to JDK 7 or higher release for
    64-bit zip format support.
