[Viacheslav Kabanovich (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-6091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12522603#action_12522603 ] 

Viacheslav Kabanovich commented on JBIDE-6091:
----------------------------------------------

java.util.ConcurrentModificationException is thown during iteration in org.eclipse.wst.xml.core.internal.catalog.Catalog while meta model is being loaded. Though list catalogElements is not synchronized, usage of Catalog instance looks thread safe so that it is not clear what can be the cause of the problem.

Taking into account, that metamodel loading failure is a very severe issue, we can work it around by providing a dummy entity resolver for meta xml files in runtime. We have xml and dtd checks in automatic tests so their is no need for that in runtime. With a dummy entity resolver, WTP's Catalog will not be invoked at metamodel loading.
