Description

This issue appears in Tomee 7.1.4 and is a blocker for our project to upgrade to 7.1.4.  In the openejb-core-7.1.4 jar, some code that was in org.apache.open.ejb.assembler.classic.Assembler that is causing the ear file in the apps folder to fail on deployment.  

If i replace the openejb-core-7.1.4 jar with openejb-core-7.1.1 jar, I do not get the error.   

Here is the stacktrace on startup.
