[Checkers] Javari Test cases

[Mahmood Ali]

Hi Telmo,

> Both have been fixed.
Great!  I should say that I am bit confused on how Javari Checker  
handles primitive types and the need to override  
BaseTypeChecker.isSubtype().  I realize that adding ReadOnly to  
primitive types will lead to a lot of errors (when passing them to  
Object for example).

Raw has given a lot of trouble in IGJ too.  It makes the code unsafe.
I think that it's safe for you now just to ignore that test case.  You  
can comment it out or something.
