Viacheslav Kabanovich commented on JBIDE-7969:
----------------------------------------------

I have managed to reproduce a similar exception:

org.eclipse.jface.text.BadLocationException
	at org.eclipse.jface.text.TreeLineTracker.fail(TreeLineTracker.java:1061)
	at org.eclipse.jface.text.TreeLineTracker.lineByOffset(TreeLineTracker.java:271)

	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

I have created method 
	@Inject
	public String getX( @Named String a) {
		return a;
	}
which was the last method in a class file.

Then I manually reformatted it to 
	@Inject
	public String getX(  

			@Named  			
			
			  String a) {
		return a;
	}
with 10 empty lines instead of 1 left here for readability.
Then I deleted each set of spaces by selecting it all and using Delete button.
Finally, I started quickly repeat Undo-Save-Redo-Save with fast keys. Several rounds resulted in the exception.
