I cannot reproduce the issue. Could you please provide more details such as the mwe2 file and the exact location of the comment tokens?

btw: I just tried with a fresh Eclipse 3.7 + Xtext 2.0.0.v201106070531 and I
can reproduce this bug...

Comment 6 Sebastian Zarnekow CLA 2011-10-24 12:48:13 EDT 
I tried to reproduce the bug with the attached file with different patterns but did not see the exception.

What I tried:
Move opening comment token (/*) a couple of line up / down (fast)
Same for closing token
Tried the same slowly (waiting for the reconciler to kick in)
Tried the same with the complete comment section
Tried the same with a couple of lines surrounding the opening / closing sequence.

Please describe very detailled what you do to reproduce the bug (e.g. 5 lines up, 2 down, 5 up, 7 down, 1 down) and reopen the ticket if it succeeds with the latest builds.

Steps to reproduce this Bug on my Mac with Xtext 2.0 on Indigo


1 Workflow {
2  
3   bean = StandaloneSetup {
4       scanClassPath  = true
5       platformUri = "${runtimeProject}/.."
6       registerGenModelFile = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
7       registerGenModelFile = "platform:/resource/org.eclipse.xtext.common.types/model/JavaVMTypes.genmodel"
8   }

1) Open the org.eclipse.xtext.example.domainmodel example
2) Open the Workflow GenerateDomainmodelLanguage.mwe2
3) Add a comment (/* */)  before  line 3 'bean = StandaloneSetup {' 
4) Remove the closing element of the comment (*/)
5) Add */ before the closing brackect } in line 8
6) Remove  */
7) Add */ after the closing bracket in line 8
