Symptoms

Tomcat application using JDBC 12.2.0.1 fails with java.nio.BufferUnderflowException: null exception.
<Patch 29286176> has been applied.

This happens almost as soon as the Application comes up.
Also, this error only happens in production environment; it does not reproduce anywhere else.
Production environment is data guarded to a DR site. Even bringing DR dataguard database up does not reproduce the error.
