java.lang.NullPointerException at org.jboss.ejb.txtimer.Data

[jkahng2000]

I am new to JBoss. I have a simple test with one entity and one session bean. It worked ok with 4.0.5. When I tried 4.2.0CR1, I get his error at startup of JBoss:

java.lang.NullPointerException
at org.jboss.ejb.txtimer.DatabasePersistencePolicy.listTimerHandles(DatabasePersistencePolicy.java:147)

I am using Postgres 8.2.3. Any help would be appreciated.

I had a working ear on JBoss 5.0.0Beta1. When I tried to switch to JBoss 5.0.0Beta2 I get this same error. I have no idea what could be causing this, is it a bug in JBoss 5.0.0Beta2?

The ejb that fails to install is using a MS SQL datasource.

If you require any more information I am happy to provide it.

Thanks.
