I just checked the latest version of Nutch out of SVR, and I noticed
that I was getting an ExceptionInInitializerError whenever Query's
static parse method was called. I isolated the call in a JUnit test
and the problem persisted, leading me to believe that it originated
from the Nutch source. Here's the stack trace:
