javaagent enhancer (PCEnhancerAgent) ignores persistence units after the first
in persistence.xml
-------------------------------------------------------------------------------------------------
Key: OPENJPA-674
URL: https://issues.apache.org/jira/browse/OPENJPA-674
Project: OpenJPA
Issue Type: Bug
Reporter: Dinkar Rao
A persistence.xml file has multiple PUs defined. A program makes use of a PU
which is NOT the first PU in the list. The classes are not enhanced at build
time, but are enhanced at runtime via the javaagent. No anchor arguments are
passed to the javaagent.
Because PCEnhancerAgent ignores PUs following the first, OpenJPA tries to use
an appropriate runtime enhancing strategy for a class, but is not always be
able to. The program gets this error back:
Error Message: [Error while processing persistent field <blah>
Error details: The accessor for field getTheAddress in type <blah> is private
or package-visible. OpenJPA requires accessors in unenhanced instances to be
public or protected. If you do not want to add such an accessor, you must run
the OpenJPA enhancer after compilation, or deploy to an environment that
supports deploy-time enhancement, such as a Java EE 5 application server.
The root problem is that the javaagent choses only the first PU's classes for
enhancement, and ignores the remaining PUs from persistence.xml. A workaround
is to explicity specify the PU referenced by the program as an argument to the
javaagent.
