I was taking a look at how regex was handled in this plugin, and ran across this:
It looks like the plugin never actually calls close on either reader. This will leak file handles and potentially system/OS buffers for each build log (and build logs can get huge).
This method should close the outside wrapper / buffered reader.

[FIXED JENKINS-25800] Ensure BufferedReader in parseLog is closed
Added a try/finally block around the reader, so it doesn't leak resources. BufferedReader will automatically call close on the FileReader it wraps.
Submitted a PR to the project to add a try/finally block.
