-------------------------------------
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.
