Description

Starting with tomee plus 7.1.2, ear files are failing deploying on startup.   In the openejb-core-7.1.2 jar, some code that was introduced in org.apache.open.ejb.assembler.classic.Assembler that is causing the ear file in the apps folder to fail on deployment.   Specifically this for loop introduced at line 829.    

for (Map.Entry entry : appContext.getProperties().entrySet()) {
if (Module.class.isInstance(entry.getValue()))

{ appContext.getProperties().remove(entry.getKey()); }

When I put the class from the 7.1.1 jar in the jar, I do not get the error.   Here is the stacktrace on startup.
