When saving a java file the IDE reports the attached exception. In addition, a 
dialog window come up informing user that the file has changed on disc, would 
you like to reload?

At this point, the file can not be saved. Causing the reloaded copy to be 
brought in from disc makes the NB copy empty, and the on disc copy empty 
resulting in user data loss.
