I was using the wrong DLTK. Now I'm using the right one, and I have the
same problem.
I unpacked the dltk zip into the eclipse directory (actually, into ..,
since the zip included an "eclipse" node). I re-downloaded the antlrdt.
Unpacked it into eclipse. Still the same exception.
Does antlrdt bundle the antlr libraries?
