Description Knut Wannheden CLA 2011-10-27 15:39:55 EDT 
The following Xtend2 file results in the dreaded "An internal error occurred during: "XtextReconcilerJob"." dialog popping up:

class Other<T> {
	def foo() { 
	  	bar(i|i.toString)
	}
	def bar((Object)=>String o) {
	}
}

Here's the stack trace:

Comment 1 Knut Wannheden CLA 2011-10-27 15:48:19 EDT 
Raising to major as this problem seems to occur with any Xtend class using generics.
Comment 2 Holger Schill CLA 2011-10-27 16:55:22 EDT 
I will have a look at that this night (US GMT-4).
