Josh Elser commented on ACCUMULO-2997:
--------------------------------------

bq. This commit simply updates the java comment with the issue number of this JIRA. It has
not been fixed.

Yes, that's accurate.

bq. The comment implies that the race condition is not an issue.

I read "the increase case should handle this and prevent deadlock" as a change that should
be made.

> there is a race condition here... the active count could be higher by the time
> we decrease the core pool size... so the active count could end up higher than
> the core pool size, in which case everything will be queued... the increase
> case should handle this and prevent deadlock
