Add tests for immutability of sets returned by builder.
Minor javadoc changes:
 - removed NullPointerException comments, these are generally not commented
   as it's always assumed null parameeters are illegal unless documented
   otherwise.
 - revised '@exception' back to '@throw', which is the preferred
   of the two synonomyous tags.
 - some language clarification
