Runtime Enhancement only processes first persistence unit defined in
persistence.xml
------------------------------------------------------------------------------------
Key: OPENJPA-96
URL: https://issues.apache.org/jira/browse/OPENJPA-96
Project: OpenJPA
Issue Type: Bug
Components: jpa
Reporter: Kevin Sutter
(This Issue may be related to OPENJPA-9, but since that one was specific to
static PCEnhancing, I thought I would open a separate Issue. Just in case the
solutions are separate.)
I'm using dynamic runtime enhancement via the -javaagent parameter. It seems
that only the first persistence-unit defined in the persistence.xml is being
processed for the runtime enhancement. If the persistence.xml has only one
entry, no problem. But, if it has more than one entry, then only the first
persistence-unit definition is being processed for the dynamic enhancement.
When I turn trace on, I get the following message when the runtime enhancement
works:
8312 my persistence unit INFO [main] openjpa.MetaData - Found 1 classes
with metadata in 0 milliseconds.
8943 my persistence unit TRACE [main] openjpa.Enhance -
"com/ibm/ws/persistence/tests/simple/TestEntity" requires runtime enhancement:
true
9043 my persistence unit TRACE [main] openjpa.MetaData - Loading metadata
for "class com.ibm.ws.persistence.tests.simple.TestEntity" under mode
"[META][QUERY]".
When this p-u definition is not first in my persistence.xml, the "8943" message
is missing and my test fails:
8512 my persistence unit INFO [main] openjpa.MetaData - Found 1 classes
with metadata in 0 milliseconds.
8522 my persistence unit TRACE [main] openjpa.MetaData - Using metadata
factory "[EMAIL PROTECTED]".
8522 my persistence unit TRACE [main] openjpa.MetaData - Loading metadata
for "class com.ibm.ws.persistence.tests.simple.TestEntity" under mode
"[META][QUERY]".
I eventually get the following message when running the testcase:
<4|false|0.0.0> org.apache.openjpa.persistence.ArgumentException: Attempt to
cast instance "[EMAIL PROTECTED]" to PersistenceCapable failed. Ensure that it
has been enhanced.
FailedObject: [EMAIL PROTECTED]
