Update
Sorry if I wasted anybody's time on this. It seems the breakdown was actually with ANTLRWorks. I guess sometimes it can get a little buggy. The actual test failure is was not a false negative, and should probably be the preferred result given a discrepancy between the two.
-------------
Hello,
I was cleaning up my grammar rules, and everything seemed fine while debugging in ANTLRWorks [1], however, the same test case [2] ran in the test suite fails with XtextSyntaxDiagnostic: null:5 missing EOF at '\n'. I noticed the root cause was some accidental whitespace added to a blank line, but this same case didn't cause any problems before my changes.
This is the first time I've seen a test case fail that was fine in ANTLRWorks. Are there additional syntactic validations other than those defined by ANTLR that I need to consider, or is this more likely a failure in how the test case is written?
Any additional insight into the issue would be greatly appreciated.
Cheers, and thanks for your time!
