Created attachment 918390 [details] reproducer org.jboss.as.controller.client.impl.ClientConfigurationImpl 052 static ExecutorService createDefaultExecutor() { 053 final ThreadGroup group = new ThreadGroup("management-client-thread"); The ThreadGroup is never cleaned up and creates a memory leak Reproducing: Start an out of the box build. I used a snapshot EAP 6.3 build of July 9th. Run the attached standalone program. It will do a loop creating a connection, and destroying it (try-with-resources) When it display 240.000 take a heap dump. The dump will contain an equal amount of ThreadGroup objects as connections have been made. The program will show memory calculations. These are not very precise of course, but the heap dump is very clear.
