This is now resolved. So, for anyone else who experiences this issue, it was the Oracle 11g ojdbc6.jar driver:
1. 11.1.0.6.0-Production (linux) => Connections Leak
2. 11.1.0.6.0-Production+ (win) => Connections Leak
3. 11.1.0.7.0-Production (downloaded) => NO Connections Leak
4. 11.2.0.1.0 (downloaded) => NO Connections Leak
