[Checkers] parser-tests tests

[Mahmood Ali]

Hi Matt,

I was wondering what the status of implementing ARRAYS convention in  
the Javac parser.  I remember you suggesting that it should be done  
within the framework rather the Parser, but I see that Parser is  
handling part of it.

r42631 log note is: 'Add support for parsing using the "arrays"  
convention (not yet the default)'

Also, I cannot get the parser-tests to pass.  Below are the steps I  
have taken.  Please note the following:

annotations/langtools      -- the latest hg jsr308 langtools
annotations/langtools-old  -- r2641 -- first build-able version since  
r2631
annotations/checkers       -- r2641

Any suggestions?
