Applies to:
JDBC - Version 12.1.0.2.0 and laterInformation in this document applies to any platform.
Symptoms
On : 12.1.0.2.0 version, Thin JDBC driver
UCP cannot create the connection pool using a wallet for authentication.
Tests done:
1) Code does work with Oracle Database 11.2.0.4.0 using the ojdbc6.jar and ucp.jar from 11.2
2) Specifying user and password directly would work, but isn't acceptable. (not using Wallets)
3) Connecting directly with wallet, but without UCP also works (just to prove that wallet setup is ok)
4) Not able to make it work using JDBC and UCP 12.1.0.2.0
Project Constraint: Has to work with Java 7
