Thread Leak - Excessive number of pools

[morph166955]

I've been noticing my average thread count rising a little every day. I went to investigate it and I find 380 of these pools have been created. It's unclear to me what is causing them but something seems to not be closing or dumping...

I'm on SNAPSHOT 3625 currently.
