cannot reproduce locally on mac

[cdietrich]

e.g. for 7 hours here https://ci.eclipse.org/xtext/job/xtext-eclipse/job/PR-860/2/console

@szarnekow could you please have a look at the stacktrace

[cdietrich]

@iloveeclipse do you know any recent changes in platform that could cause this?

[cdietrich]

JavaRefactoringIntegrationTest In xtend seems to have similar issue
http://services.typefox.io/open-source/jenkins/job/xtext-xtend/job/cd_eclipse_issue841c/4/console

[iloveeclipse]

can you create jstack mit locks data (jstack -l). I would guess main and modalcontext threads deadlocked on workspace ressources or something like that.

[cdietrich]

hmmm have to figue our how to do that from within java since nobody gives us shell access anywhere :(

[cdietrich]

here is a screenshot created programmatically. i wonder why the project looks "closed"

[cdietrich]

here is the jstack log file

jstack.log

i dont see where the guys are waiting for
