/**
 * JAX-RS Integration Test.
 *
 * Testing Plan:
 * 1. Verify that methods annotated with @GET are mapped to the controller.
 * 2. Verify that params are parsed using the @QueryParam are actually the values on the URL using the ?queryparamkey=value
 * 3. Verify the exception mapping stuff is well understood
 *     a. pass a flag parameter that instructs the controller to throw a mapped exception - then verify we see the status + body we expect.
