Description

The ExecuteAndWaitInterceptor processing appears to only execute as expected for the first run-through for any given session. 

This can be seen interactively using the Struts2 Showcase "Execute and Wait Examples", with the wait processing only functioning during the first attempt through each example in the same session.  Clearing the session in the browser gives the expected wait behaviour again, but only one time (until clearing the session again).

After debugging the ExecuteAndWaitInterceptor flow, it appears that the removal from the SessionMap did not perform as expected, resulting in a state divergence with the underlying session.

A PR that attempts to fix the behaviour will be submitted soon.
