> If I do a redeploy of a war that contains a JDBC Control that has been in use, then my JDBC Controls throw an NPE when used after the redeploy completes. I believe that the cause of this is that the redeploy is causing the session (which contains the JDBC Control) to be serialized. There is a field in the JDBC Control called _resources that is transient so it gets dropped. After the redeploy / deserialization of the session, the _resources remains null but is then used in onRelease().
> Repro:
> - edit build.properties for derby.jar location
> - edit src/org/apache/beehive/samples/petstore/controls/data/DBProperties.java for where you want derby data
> - ant deploy-beehive build war
> - cp petstoreWeb.war $CATALINA_HOME/webapps
> - http://localhost:8080/petstoreWeb/
> - Click initDB
> - Click stopDB
> - cp petstoreWeb.war $CATALINA_HOME/webapps
> - Click initDB
> - Getting an NPE here, but really should be okay.
> - If you wait until the session times out, then you can move on and the NPE doesn?t appear again until your next redeploy
