Lucas Smith created OPENJPA-2184:
------------------------------------

             Summary: Exception when <exclude-unlisted-classes> element is used within
persistence.xml
                 Key: OPENJPA-2184
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2184
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 2.2.0
         Environment: JavaSE
            Reporter: Lucas Smith


Here is my persistence.xml content:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  <persistence-unit name="derbyPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
      <property name="openjpa.ConnectionDriverName" value="org.apache.derby.jdbc.ClientDriver"
/>
      <property name="openjpa.ConnectionURL" value="jdbc:derby://localhost:1527/hibernate;create=true"
/>
      <property name="openjpa.ConnectionUserName" value="hibernate" />
      <property name="openjpa.ConnectionPassword" value="hibernate" />
      <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(SchemaAction='drop,add,deleteTableContents',IgnoreErrors=true)"

      <property name="openjpa.jdbc.DBDictionary" value="derby(NextSequenceQuery=VALUES
NEXT VALUE FOR {0})"/>
    </properties>
  </persistence-unit>
</persistence>
{code}

Such configuration produses the following exception:

I have already used java 5, 6 and 7 compilers. They all give the same exception.

However, when I delete <exclude-unlisted-classes>false</exclude-unlisted-classes>
element and declare classes explicitly (using <class> elements) everything works like
a charm.

I am using Open JPA in Java SE environment. I have 'openjpa-all-2.2.0.jar' in my class and
build paths.
