[jira] [Commented] (TOMEE-2919) java.util.ConcurrentModificationException error deploying ear in TomEE Plus 7.1.4

["Geeth Narayanan (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TOMEE-2919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17526015#comment-17526015 ] 

Geeth Narayanan commented on TOMEE-2919:
----------------------------------------

We faced the same issue:

In openejb-core within org.apache.openejb.assembler.classic.Assembler

 

                for (final Entry<Object, Object> entry : appContext.getProperties().entrySet()) {
                    if (Module.class.isInstance(entry.getValue())) {
                        appContext.getProperties().remove(entry.getKey());
                    }
                }

This remove causes concurrent modification exception.

Whereas in 7.1 or 8.x, it does this:

                for (final Entry<Object, Object> entry : appInfo.properties.entrySet()) {
                    if (! Module.class.isInstance(entry.getValue())) {
                        appContext.getProperties().put(entry.getKey(), entry.getValue());
                    }
                }

> 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.
