    ****************************************************************
    There is a potential for a deadlock to happen if the customer is
    using an Oracle JRE and has the Liberty JSON logging feature
    enabled.  When encountered, the server will startup normally up
    to the point where the CWWKE0001I, CWWKZ0058I, and CWWKF0012I
    messages are issued.  Shortly afterwards, the server will become
    unresponsive and no additional logging will be performed.
    

Problem conclusion

Temporary fix

  • User can use an IBM JRE to avoid the potential deadlocks.
