Which Eclipse version do you use? (In reply to comment #2) > Which Eclipse version do you use? Eclipse Modeling Tools Version: Indigo Service Release 1 Build id: 20110916-0149 plus: - Xtext SDK 2.2.1 - MWE2 runtime SDK - XML Editors - Subversive + JavaHL - m2e - Tycho Project Configurators There were recent changes in that field. You do not recall the files that caused the infinite loops? (In reply to comment #4) > There were recent changes in that field. You do not recall the files that > caused the infinite loops? I do remember which projects I was working on, but two months later I don't have precise recollections of which files were involved, sorry. 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)

Stack Trace
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. |
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.
