Completely agree Deron, these are becoming stale and obsolete with the APIs
being enhanced and the javadocs being left behind. In the past I actually
tried to fix some, but as you mentioned there is a lot and we need a
community effort here.

Another approach is to make javadocs update MANDATORY for PR acceptance,
meaning that, if you touch a given file, you fix any javadoc related to
that file.

Thoughts ?
