Jersey root resource objects are created "per-request." They are not
singletons like Servlets. The class constructor will be called before
every request, and is the appropriate place to put per-request
operations.
However, if you're using this to initialize data that is always the
same for every request, you might want to consider another option,
such as writing a ContextResolver that can initialize the data once
and make it available to root resources.
