[jdom-interest] lookup for the parser

[Jason Hunter]

I just timed how long it takes to execute the build() method up until to
the parse step.  The first time though takes a bit of time due to class
loading.  The second time through takes "0" milliseconds.  It's faster
than the resolution on the system clock.  Seems it's not expensive
enough to worry about.
