Description of problem:

AutoConnectionCloser class in the ejb remoting API keeps a cache of all remoting connections.  These objects are not deleted until the JVM shuts down (this class has a JVM shutdown hook).  This causes a memory leak for client applications: particularly multi-threaded ones - in our case, we create a connection for each EJB invocation, which adds up quickly over time.

Version-Release number of selected component (if applicable):

Tested on JBoss EAP 6.2 (module is jboss-ejb-client-1.0.24.Final-redhat-1)

How reproducible:

Create a remoting client as described here:
https://docs.jboss.org/author/display/AS72/Scoped+EJB+client+contexts

In our case, our client is multi-user/multi-threaded.  In high-concurrency/high-throughput test runs, we encounter OutOfMemoryErrors that can be traced back to the org.jboss.remoting3.ConnectionImpl object, which is cached in AutoConnectionCloser

Actual results:

Memory leak of approx. 2k per connection

Expected results:

An option to disable caching would be great!
