I've seen this as well but I haven't been paying attention since it seems to 
be in the inner workings of the IDE. Probably an issue should be filled to 
get at least clarification.

OK, so my platform application utilizes the "View IDE Log" action.  
Everything works fine, but I see this stack trace happen every time I choose 
"View IDE Log":

Has anyone else seen this?  It doesn't hinder the application nor stop me 
from seeing my logs.  It just pops up in the "Run" window of the IDE running 
the platform application.
