ORA-28040: No matching authentication protocol error

We have got following error in Application logs and we were made to cross-check our JVM settings.

It was determined that removing JVM parameter -Doracle.jdbc.thinLogonCapability=o3 will fix the ORA-28040: No matching authentication protocol error. I remembered that we added this JVM parameter for certain applications during the WebSphere 7 upgrade. The problem was that certain applications running on WebSphere 7 with JDK 1.6 and ojdbc6.jar was not able to login to the Database. This was because of an Oracle driver “issue” when dealing with external 3rd party JCE libraries such as BouncyCastle.
