We have a REST API where clients can supply parameters representing values defined on the server in Java Enums.

So we can provide a descriptive error, we add this

Probably you can implement generic static lookup method.

Like so

public class LookupUtil {
   public static > E lookup(Class e, String id) {   
      try {          
         E result = Enum.valueOf(e, id);
      } catch (IllegalArgumentException e) {
         // log error or something here

         throw new RuntimeException(
           "Invalid value for enum " + e.getSimpleName() + ": " + id);
      }

      return result;
   }
}

Then you can

public enum MyEnum {
   static public MyEnum lookup(String id) {
       return LookupUtil.lookup(MyEnum.class, id);
   }
}

or call explicitly utility class lookup method.
