That is neither the smallest possible code to show the problem, nor
self-contained. My guess would be that "reader" in your offending
line is the culprit. It isn't shown anywhere else in your code so,
from the evidence you've provided, it is reasonable to think it might
be null.

Doc id. It's in the javadocs.
