Description

We've been seeing some build failures on some machines due to an issue with OpenJPA (specifically, the changes made in OOZIE-1377).

We see these two cryptic errors in the output from the build:
[INFO] — openjpa-maven-plugin:2.2.2:enhance (enhancer) @ oozie-core ---
An error occurred while attempting to determine the version of "file:/var/lib/jenkins/workspace/build/oozie/4.1.0-SNAPSHOT/source/core/target/classes/META-INF/persistence.xml".

[ERROR] Failed to execute goal org.apache.openjpa:openjpa-maven-plugin:2.2.2:enhance (enhancer) on project oozie-core: Execution enhancer of goal org.apache.openjpa:openjpa-maven-plugin:2.2.2:enhance failed: org.apache.openjpa.persistence.PersistenceProductDerivation:java.lang.ClassCastException: org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration -> [Help 1]

I saw that RAVE-245 had a similar error and their solution was to add Xerces as a dependency on the OpenJPA plugin. This prevents a classpath env issue from sometimes choosing the built-in buggy version of Xerces that Java is using by default (see OOZIE-1017), and instead to use the better version that we've been using elsewhere.

Issue Links

• is broken by: OOZIE-1377 OpenJPA runtime enhancement should be disabled and update OpenJPA to 2.2.2
• is related to: OOZIE-1017 Add test to make sure old version of Xerces isn't being used
