Application doesn't cannot be started after being stopped

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In one of jME3's tests, in the main() method, put the following code after 
app.start():
Thread.sleep(1000);
app.stop();
Thread.sleep(1000);
app.start();

What is the expected output? What do you see instead?
It is expected that the app will launch a second time normally, instead, it 
fails.

There's too much state being initialized in the Application class to allow it 
to reinitialize properly (also assuming user code to know this). Its best to 
handle this process on the context side rather than app side. Currently the AWT 
panel and canvas support this process therefore user code should use these 
types of contexts when the app should support user closing it and opening again.
