Sorry, no steps.

Comment 1 David Audel CLA 2007-05-24 10:29:22 EDT 
I did't found how to reproduce the bug.

The stacktrace show that the parser failed to create the initial recovery state and return a null recovered element.

As i didn't know what cause this failure, i can only add a null check to avoid the NPE.

*** This bug has been marked as a duplicate of bug 204662 ***
Comment 3 Frederic Fusier CLA 2007-12-07 09:54:12 EST 
Indeed the stack trace looks similar.
