Gary ,Verwers commented on LOG4J2-3619:
---------------------------------------
I have tried to create an example application that does the StackOverflowError
but I have not been successful in getting the process to stall. We have two
different scenarios which the logging stalls when logging a StackOverflowError.
I think it may be the combination of StackOverflowError and a very large
message. But my test application is not stalling. If I can create
repeatable test I will post it.
> Log4j stops logging when the log message contains a
> java.lang.StackOverflowError

> The RingBuffer Consumer stop printing logs when it comes to a log event with
> an exception connected with a StackOverFlowError attached. We have had
> this occur several dozen times.
> Both the cursor and the gate point at the same place in the event buffer and
> very quickly all the threads on the server are frozen waiting for the ring
> buffer to clear up space. But the consumer is just stuck waiting a not
> printing event. It has failed with a stack overflow from spring MVC mapping
> and it has failed with a stack overflow from Jackson JSON ObjectMapper with
> object level recursion triggering a stack overflow.
