    Description

      When running the attached reproducer application and doing a memory analysis afterwards, it looks like a memory leak, e. g.

      One instance of "org.jboss.as.ejb3.component.stateless.StatelessSessionComponent" loaded by "org.jboss.modules.ModuleClassLoader @ 0x5e0fbc2e0" occupies 936,593,520 (96.13%) bytes. The memory is accumulated in one instance of "java.util.concurrent.ConcurrentLinkedQueue$Node" loaded by "<system class loader>".

          is incorporated by

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-17510 [GSS](7.2.z) WFLY-12446 - Memory leak in StatelessSessionComponent

          • 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.
