Jon Moore commented on HTTPCLIENT-1108:
---------------------------------------

Agreed, adaptive connpool should go to 4.2 and not 4.1.x.

> Currently, the ThreadSafeClientConnManager reuses persistent connections in a round-robin
fashion: when the connection is checked back into the pool, it is added to a queue of available
connections for later use. This has the perhaps unintended effect that the client may keep
open more connections than needed, because the "last used" time keeps getting updated and
none of the connections can get reclaimed via closeIdleConnections().
> Exchanging the queue (FIFO) for a stack (LIFO) would result in extra connections actually
becoming idle for long enough to be reclaimed.
> I have a working patch for this; just need to get my act together to get it in.
