[jboss-jira] [JBoss JIRA] (WFLY-10253) ConcurrentModificationException on startup

Scott Marlow commented on WFLY-10253:
-------------------------------------
[~mhk] Could you show us the contents of the EAR that you are deploying (output of
"jar tf yourapp.ear" and also the contents of contained archives)? Mostly I am
curious if there are any persistence provider jars contained in the EAR and if yes, the
location in the EAR. I'm also interested in the location of the persistence.xml files
in the EAR as well.
This will help me understand why your hitting this and how to responde to [~swd847] point
raised in [https://github.com/wildfly/wildfly/pull/11164] about symptoms of a different
problem than the pr addresses.
Thanks!
ConcurrentModificationException on startup
------------------------------------------
Key: WFLY-10253
URL: https://issues.jboss.org/browse/WFLY-10253
Project: WildFly
Issue Type: Bug
Components: JPA / Hibernate
Affects Versions: 10.1.0.Final
Reporter: Martin Herschke
Assignee: Dmitrii Tikhomirov
standalone wildfly startup: This exception appears sporadically and is caused by
different modules and projects.
Multiple threads are used to deploy modules ({{MSC service thread 1-7}}), but a static
method {{lookupProvider}} is called. The provider list is a normal ArrayList that causes
the exception.
