JBoss hangs at Hibernate initialisation

I have an ear application, packaging a war and jboss seam and an EJB3 bean.
The Seam is only used for scheduling.

I use Hibernate, JPA 1.0, JBoss 5.1.0.GA and Oracle 11.
During deploy, the JBoss hangs after the following lines:

2011-06-20 13:20:35,140 INFO [org.jboss.jpa.deployment.PersistenceUnitDeployment] (HDScanner) Starting persistence unit persistence.unit:unitName=cs_ft.ear/lib/FT-DB-JPA-1.0-SNAPSHOT.jar#be.cs_ft.impl_FM-DB-JPA

I have this both on a local JBoss (oracle XE, log shown), as on a remote server (oracle 11).
It seems to be consuming a lot of memory, as can be seen in the process monitoring. After some time an out of memory error is thrown.

Does someone experienced this, and what can be the cause of this error?

It seems this bug was because
I also included the eclipselink dependencies in maven. (I created my project using Netbeans 7)
JBoss/Hibernate seem not be able to cope with this and give appropriate error.

After downscaling my project to hibernate dependencies only on all levels (also test), it did not have this bug any more.
I agree. Here's the link:
