   I wonder if we really need to cache the Id object. Each Id is a wrapper 
around a String. I wonder if the following would be sufficient:
   
   ```
      protected AbstractId(final String canonical) {
   -    this.canonical = Objects.requireNonNull(canonical, "canonical cannot be 
null");
   +    this.canonical = Objects.requireNonNull(canonical, "canonical cannot be 
null").intern();
      }
   ```
   
   I realize that by Caching the Id object we are saving the time it takes to 
create it, but we are also incurring the overhead of having a Cache for each Id 
type.
