I am getting a ClassCastException when using the CMP 2.x jdbc2 PM for one of my entity beans in JBoss.
Issue
-
We tried to define this bean as a "Standard Pessimistic CMP 2.x EntityBean" but then we get ClassCastExceptions while deploying because it then uses a JDBCStoreManager which is incompatible to the JDBCStoreManager2 of the new persistence manager.

You see the following exception in your server.log:
