Description Lars Vogel CLA 2015-05-26 06:31:35 EDT 
See 

I suggest to add the following to the @Optional Javadoc.

> null is an acceptable value to be set in the context, and it is different
> from a key being removed from the context.  i.e.,
> 
>     context.set(SOMEKEY, null);
> 
> means anybody listening for SOMEKEY will be injected with null.
