An application server deployed JDBC application is getting a deadlock on oracle.jdbc.driver.OracleTimeoutThreadPerVM.

Example of a stack trace with Weblogic 12.1.3 and JDBC 12.1.0.2:

This situation is similar to what is described in the following document:  JDBC Deadlock in ORACLETIMEOUTTHREADPERVM and T4CCONNECTION when Using JDBC 11.2 with WebLogic 10.3 or 12.1 (Doc ID 1423425.1)

However the JDBC driver is version 12.1.0.2 which means that this issue is not caused by bug:12808945 JDBC DEADLOCK IN ORACLETIMEOUTTHREADPERVM AND T4CCONNECTION.
