Git Pull Request:
https://github.com/jbossas/jboss-eap7/pull/4455
Steps to Reproduce:
Hide

1. Deploy failedappleak.war
2. Capture a heap dump
3. Check the deployments map with an OQL like below (it should return a size of 0):

SELECT deployments.m.size FROM io.undertow.servlet.core.ServletContainerImpl

Or the attached ~~WFLY-17365~~.btm adds extra tracing making it easy to see if the remove happened or not.

If a deployment fails, it has an entry that is not removed from the undertow ServletContainer deployments map. That could be an unwanted classloader leak or cause unwanted behavior like undertow ServletContextImpl.getSession always iterating over this failed app's session manager to check for sessions.
