The call stack is below. There are some catches in some of the calls, but none are catching any of these and logging it.  The StackOverflowError is thrown up, but PassivateTask is running in a separate thread, so it appears the exception is thrown up to the JDK classes below and is never logged.

We need to catch Throwable at some point and log a message, also need to make sure that we are taking the correct action when it occurs since it failed to passivate.

java.lang.Throwable
    java.lang.Error
        java.lang.VirtualMachineError
            java.lang.StackOverflowError
