Subject [jira] [Commented] (OAK-8071) Logging to detect commits carrying over from previous GC generation can block other threads from committing
Date Tue, 26 Feb 2019 13:48:00 GMT

Michael Dürig commented on OAK-8071:

Good point, I'll merge this into my branch.

 

OTOH, I while the new monitoring is quite sophisticated this way, I figured out that I cannot
backport it to 1.8. There are zillions of conflicts. I'm currently trying an alternative and
simpler approach logging warnings instead. The JMX approach is still useful though for trunk
I think. Will share another branch soon.
