Comment 1 Ed Willink CLA 2013-02-05 17:54:57 EST 
The problem is that an embedded OCL expression ends with a comment, and so when the terminating ';' is appended the terminating ';' is commented too.

Workaround; add a new line at the emd of the commenrt or remove the commented out code.

[Developers note; the serialization speed of this example is dreadful. Worth comparing with Indigo and trying to isolate as an OCL or Xtext inadequacy.]

Exception not reproducible on M4; looks like an Xtext improvement.
