["Dawid Weiss (JIRA)" <ji...@apache.org>]

Dawid Weiss commented on LUCENE-5716:
-------------------------------------

This is just a note to self. I requested an open source license for the most recent YourKit profiler (graciously donated by the company -- yay!). There is a new feature I haven't seen before -- probes, exactly in the shape and form I always imagined them to be (I have been a fan of aspectj, but this is done via agents, so it allows modifications of system classes I believe).

Very cool. This could be used to track other resource leaks (sockets, etc.). If combined with JUnit rules, it could even detect such leaks at class or method level.
