broken code model cache
Comment 3 Vladimir Kvashin 2015-09-23 21:23:10 UTC 
Isn't it the same problem with FileImpl hashCode? Unfortunately can't see message log from home :)
Comment 4 Vladimir Kvashin 2015-09-24 16:28:44 UTC 
It can occur that some client holds file and asks it for hash code while the project already closed or even deleted. (I guess this might in particular happen when calling re-parse)

fixed:
