Kemal Serkan updated OPENJPA-2157:
----------------------------------
NOTE: This occurs only for version 2.0 persistence.xml. Using 1.0
persistence.xml solved the problem for the sample. Here is the problematic
persistence.xml
<persistence xmlns="http://java.sun.com/xml/ns/persistence";
version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";>
<persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<class>openjpa.test.Living</class>
<class>openjpa.test.Human</class>
</persistence-unit>
</persistence>

> @ManyToOne @JoinColumn(name = "f_key", table = "SEC_TABL") schema tool

> when deleting the entity, NPE is thrown. There may also other effects. Here
> is the NPE stack trace in 2.2.0 version.
