I am trying to diagnose a performance issue with the grammar I have which
looks similar to the problem stated (severe performance problem / infinite
loop? in AbstractInternalAntlrParser) in a thread from 1/18/2011. The part
of the grammar in question is a small scripting language that has a
moderately complex expression tree.

I am trying to determine:
a) if this is an xtext 1.0 issue (looks like it was from the message on
b) are there some rules of thumbs to refactor this portion of the grammar to
make the performance problem go away.
