      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.

    Description

      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's ServletContextImpl.getSession always iterating over this failed app's session manager to check for sessions.

          causes

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-26755 [GSS](8.0.z) UNDERTOW-2354 - Bootstrap$WebSocketListener.contextDestroyed throws NPE after application start up error

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-24306 [GSS](7.4.z) WFLY-17365 - Failed deployment is not removed from Undertow ServletContainer's deployments map

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
