Manuel Meyer updated OPENJPA-2226:
----------------------------------
Summary: Automatic runtime enhancement only works when the class is listed
in the first persistence-unit (was: CLONE - PCEnhancer not processing multiple
PU's defined within a single persistence.xml file)

> Key: OPENJPA-2226
> URL: https://issues.apache.org/jira/browse/OPENJPA-2226
> Project: OpenJPA
> Issue Type: Bug
> Components: jpa
> Affects Versions: 2.0.1, 2.2.0
> Reporter: Manuel Meyer
>
> When multiple persistence-units are defined in the persistence.xml, only the
> first one is examined when looking for classes to enhance when using the
> automatic runtime enhancement (e.g., using the "-javaagent:openjpa.jar"
> argument). So if the project uses the following persistence.xml:
> <persistence xmlns="http://java.sun.com/xml/ns/persistence"; version="1.0">
> <persistence-unit name="unit1" transaction-type="RESOURCE_LOCAL">
> <class>unit1.SomeClass</class>
> </persistence-unit>
> <persistence-unit name="unit2" transaction-type="RESOURCE_LOCAL">
> <class>unit2.OtherClass</class>
> </persistence-unit>
> </persistence>
> In this example, when unit1.SomeClass is loaded, it will be enhanced, but
> unit2.SomeClass won't ever be enhanced.
> The exception we get is following:
> Exception in thread "main" <openjpa-2.2.0-r422266:1244990 nonfatal user
> error> org.apache.openjpa.persistence.ArgumentException: An error occurred
> while parsing the query filter "select t from OtherClass t". Error message:
> The name "OtherClass" is not a recognized entity or identifier. Perhaps you
> meant SomeClass, which is a close match. Known entity names: [SomeClass]
