Created attachment 210726 [details] stack dump 1 Xtext version 2.2.1, a sufficiently large workspace with an Xtext project that imports a model from a separate project. I think I was editing the ecore when Eclipse froze completely. Also xtend2 is used in some projects, but looking at the stack dump I can't see any traces of xtend working. In the underlying cmd console tons of messages were running through mentioning some resource(s) the were found to be empty, IIRC this concerned a .java file corresponding to the model. Sorry, I couldn't capture that output. Using Java VisualVM I saw one thread consuming 100% CPU, and I took two sample thread dumps, to be attached here. Look for "Worker-27". Since no progress could be observed I had to kill the Eclipse process. The same problem already happened an hour or so ago.

There were recent changes in that field. You do not recall the files that caused the infinite loops?

I have the same problem in a xtext created editor. Look at the following situation: File in Editor: domain MyDomain { entity A } If I hit ctrl-space after the 'A' I get the situation described in this bug. On the other hand if the file looks like the following: domain MyDomain { entity A entity B { name : String } } And I do the same as before (ctrl-space after 'A') everything works nicely. The grammar at that particular point is: Entity: 'entity' name=ID (doc=STRING)? (ann+=Annotations)* '{' where STRING starts with ' or " and Annotations starts with 'annotation' See also the attached stack trace (look at Worker-12 and main)

Forget my two added comments. I posted this to the wrong issue. I'm really sorry about that.
Unfortunately I cannot see, how this happened, nor can I reproduce it. It might have been fixed already. Please reopen, when it happens again.
