I'm using jboss 7 with a plain old oracle datasource. (pool of 200 connections, all with the same username/password)
Profiling shows that a lot of time is spent in the above method. It for instance calls a synchronized method (getConnectionProperties), which is problematic in a parallel environment. 

Knowing that my datasource only contains 'matching' connections, i wonder whether there is a way of skipping the properties comparision step. 

Any ideas ?
