Hi, Semyon.
NPE occurs when we initialize KFM on the Toolkit thread, but this is 
only a part of the bug, another issue is that we will use cached 
keystrokes on the toolkit thread. But this keystrokes is bound to the 
appcontext so we should not use objects which connect to the application 
on the toolkit thread. This code should be carefully checked to remove 
appcontext related stuff from the toolkit thread.
