 * This Jersey specific service provider will install the JAX-RS dynamic
 * feature which on its turn will install filters for JAX-RS resources
 * that check roles or deny all access.
 *
 * 
 * Note this extra service is needed, so the MP-JWT implementation code can be in
 * a server/container jar, which is typically not scanned for the Provider
 * annotation, which would normally cause the dynamic feature to be installed.
