@SuppressWarnings("null") really needed?

[olegk]

Hi Sebastian,

Since your last commit my Eclipse pops up a warning saying 'Unnecessary
@SuppressWarnings("null")'. What is the purpose of this annotation? Is
it needed?

Well, without it _I_ get a warning that the variable could be null...

I assume we must have different local Eclipse settings.

Not sure how to deal with the problem - seems to me Eclipse is being
too literal about the warning in your case.

I found these regarding the annotation:

Eclipse 3.4 & 3.5 changed the way they handle warnings.  For example, in 3.4
a private inner class with unused public variables would not warn about
unused variables.  In 3.5, it does warn (and adding a suppression for 3.5
will cause 3.4 to warn about an unnecessary suppression).  I assume there's
similar changes for null handling.
