Wildfly 9 - Probleme excluding Quartz dependency

Question

I'm using Wildfly 9 to deploy two web applications (wars) simultaneously. I recently upgraded the version of quartz used by one of the applications and now I'm getting the following error when I deploy:

Caused by: org.quartz.SchedulerConfigException: Unable to instantiate InstanceIdGenerator class: org.quartz.simpl.SimpleInstanceIdGenerator cannot be cast to org.quartz.spi.InstanceIdGenerator [See nested exception: java.lang.ClassCastException: org.quartz.simpl.SimpleInstanceIdGenerator cannot be cast to org.quartz.spi.InstanceIdGenerator]

As far as I can tell, Wildfly doesn't use quartz (does it?), so I assume there is a classloading confilct with the quartz dependency from the other application. I tried to add a quartz exclusion in Jboss-deployment-structure, but the conflict persists. This is my jboss-deployment-structure:

I can't find much in the way of documentation on classloading conflicts between two deployed wars. Am I doing something wrong here? Any help would be appreciated. Thanks.

Quartz - 2.2.1

Wildfly - 9.0.1

How is the quartz library set up? Is it created as a WildFly module or directly resides in the war? — Quincy, Jun 01 '16 at 08:27

I fixed the issue by excluding Spring scheduling. My Quartz exclusion was working, but Quartz was still getting in via the dependency chain.
