How to troubleshoot Exception: java.lang.ThreadDeath

Since putting a custom plugin in place, that make an external call to a REST service, I have been getting redis queue alerts.

The redis queue typically maintains a 0 queue, but recently it spikes to 14,000 then back down to 0 in about 2 minutes.

I have a feeling it has to do with my new plugin. Is there a way to get more details about the following error without running with -vvvv

Exception: java.lang.ThreadDeath thrown from the UncaughtExceptionHandler in thread "Thread-45"

What thread is throwing the exception.
