RH Bugzilla Integration commented on AS7-6396:
----------------------------------------------

wfink at redhat.com made a comment on [bug 911297|https://bugzilla.redhat.com/show_bug.cgi?id=911297]

Description of problem:


If the pool for entity-bean instances is added to the ejb3 subsystem and CMP is used a NullPointerException is thrown if the instances is obtained from the instance-pool. This will be the second access to the entity.

The problem is that the PersistenceContext is not set correct if the instance is obtained from the pool.


How reproducible:
Add a configuration for CMP entities:
<subsystem xmlns="urn:jboss:domain:ejb3:1.4">
...
<entity-bean>
<bean-instance-pool-ref pool-name="entity-strict-max-pool"/>
</entity-bean>
<pools>
<bean-instance-pools>
...
<strict-max-pool name="entity-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/>
</bean-instance-pools>
</pools>

Actual results:
Caused by: java.lang.NullPointerException
