Problem summary

  • For applications which excessively create new parser instances
    this eliminates contention for a lock on the class object which
    under high load may cause threads to deadlock.

  • This defect will be fixed in:
    5.0.0 SR12 FP5
    6.0.0 SR9 FP2
    .
    JVM has been modified to address the deadlock.
    .
    To obtain the fix:
    Install build 20110520 or later
