             Summary: java.util.ConcurrentModificationException error deploying ear in TomEE Plus 7.1.4
                 Key: TOMEE-2919
                 URL: https://issues.apache.org/jira/browse/TOMEE-2919
             Project: TomEE
          Issue Type: Bug
          Components: TomEE Core Server
    Affects Versions: 7.1.4
            Reporter: Michelle Solon


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.
