RFR [4682009] Typo in javadocs in javax/naming

[Ivan Gerasimov]

Hello!

May I please have a review of the fix?

It's not meant to be a proof reading, I only fixed some obvious typos.
Some of them were reported at the time of java 1.4, so it is probably 
the time to have them fixed.

Sincerely yours,
