Checks types of parameters annotated @PathParam, @QueryParam, etc. The type of the annotated parameter, field or property must either:
  1. Be a primitive type.
  2. Have a constructor that accepts a single String argument.
  3. Have a static method named valueOf or fromString that accepts a single String argument (see, for example, Integer.valueOf(String)).
  4. Have a registered implementation of ParamConverterProvider JAX-RS extension SPI that returns a ParamConverter instance capable of a "from string" conversion for the type.
  5. Be List<T>, Set<T> or SortedSet<T>, where T satisfies 2, 3 or 4 above. The resulting collection is read-only.
