Description Ed Willink CLA 2009-12-30 02:40:35 EST 
The LPG 2 parser gives slightly different diagnosis of errors causing the bcaktracking tests to fail.

The use of ERROR_TOKEN in EssentialOCLErrors.g was slightly pragmatic.

While the change is a nuisance, it may provide an opportunity to do better; this may be an area where the parser has improved.
Comment 1 Ed Willink CLA 2010-06-26 10:52:16 EDT 
The backtracking parser supports multiple diagnosis in editors, which are now supported by Xtext. The backtracking parser is heading for deprecation and so further development is unlikely.

Closing WONTFIXes.
