We should note this change of behavior in the changelog. I am OK with
it, but I think we discussed it a while back and decided not to do it
due to concerns that removing the synch could result in hammering the db
engine with concurrent bursts of createConnection requests when load
spikes happen when maxIdle is used. Personally, I don't see a problem
with this, but we should point it out to users. I will also run some
load tests with db engines I have available.
