cd async-void-ejb
mvn clean package dependency:copy-dependencies
      2. Add an ApplicationRealm user (jboss/jbossjboss#2) to a standalone server.

      Add command line option -Djboss.remoting.pooled-buffers=false. Though some reported a big performance impact.

    Description

      OOME in direct buffer happens when a remote client calls an asynchronous method which has return type void many times.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-4284 Calling remote asynchronous void method causes OutOfMemoryError in direct buffer memory

          • 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.
