Update the javadoc for the CompositeCodec class.

Change the  `ClassUtils.findClosestMatch` `failOnTie` to true.
  In the past when finding the appropriate delegate(codec) for a object and
  their were multiple delegates available the first one was returned.
  The problem is it could return a different delegate on each launch of the `findDelegate`.
  Now with `failOnTie` set to true a `IllegalStateException` is returned.

Remove deprecated constructor from CompositeCodec
