[Actionframework-users] bug: request components and changed action config

[Mark D. A. <md...@di...>]

If I turn on reloadActionConfig and if I have "request" level components, then I get this
when I change the action config file and reload a page:

java.lang.IllegalStateException: Cannot get component with "request" persistence from non-servlet thread
	at org.actionframework.ActionRuntime.getComponent(ActionRuntime.java:1448)
	at org.actionframework.ActionServlet.getComponent(ActionServlet.java:737)
	at org.actionframework.ActionServlet.processRequest(ActionServlet.java:532)
	at org.actionframework.ActionServlet.handle(ActionServlet.java:359)

This is presumably because ActionServlet stores session ids in runtime.threadSessions,
and the actionConfigFile change handling is implemented by replacing runtime by
newRuntime.
A fix would be to either copy over more state (such as threadSessions) between
the two, or to modify the existing runtime instance instead of replacing it.
