org.datanucleus.exceptions.NucleusException: Plugin (Bundle) "org.datanucleus" is already registered. Ensure you dont have multiple JAR versions of the same plugin in the classpath. The URL "file:/Users/gallavie/Documents/workspace/Darimpo/war/WEB-INF/lib/datanucleus-core-3.1.3.jar" is already registered, and you are trying to register an identical plugin located at URL "file:/Users/gallavie/Documents/workspace/libs/appengine-java-sdk-1.9.51/lib/opt/user/datanucleus/v2/datanucleus-core-3.1.3.jar."
