Any chance you could test this with 2.2.6 or even the 2.2.7-SNAPSHOT? Any
required fix would be put there, however, I'm really more interested in the
line numbers for the stack traces with recent code. Easier to map in and
figure out what's happening.
Also, do you know if woodstox is being used for the parser? If not, can you
try that?
