Description of problem:

We have migrated our application running earlier on jboss-4.2.3.GA to jboss-eap-6.2.0, after this we noticed performance issues when the application was interating with the Oracle DB while executing the stored proc

The normal execution time of the queries on oracle DB started to increase exponentially while using jboss 6.2.0, while analysing we found there were high CPU consumption on Oracle DB when the application is running in jboss 6.

On rollback to Jboss 4, the application performed very well, we were able to get expected performance results.
