Warning in POIMetadataExtracter leads to docx documents not being indexed

Customer running alfresco 4.1.4 on weblogic/oracle/rhel is experiencing the following warning when a docx document is uploaded to the repository (see attached file for full stack)

org.apache.xmlbeans.SchemaTypeLoaderException: Cannot resolve type for handle _XY_Q=space|R=space@http://www.w3.org/XML/1998/namespace (schemaorg_apache_xmlbeans.system.sE130CAA0A01A7CDE5A2B4FEB8B311707.cttext7f5btype) - code 13

This error was reproduceable when deploying alfresco 4.1.4 in weblogic 10.3.5, as a test I decided to install tomcat on the same machine and deploy the alfresco.war using the weblogic instance files (alfresco-global.properties, jdbc driver, alfresco.war from ear) Uploading a docx file in the tomcat instance does no produce this issue, it appears that we could be experiencing a library collision somewhere but can't really find the root cause, the suspecting jars that could be causing this issue are the following

./Oracle/Middleware/modules/com.bea.core.xml.beaxmlbeans_2.3.0.0_2-5-1.jar
./Oracle/Middleware/modules/com.bea.core.xml.xmlbeans_2.2.0.0.jar
./Oracle/Middleware/modules/com.bea.core.xml.xmlbeans_2.1.0.0_2-5-1.jar

The reason for this being urgent is because this warning prevents docx documents from being indexed, this does not happen in a tomcat environment running the same alfresco version.

The actual alfresco version is
