Review request for JDK-7118412: Shadowing of type-variables vs. member types

[Maurizio Cimadamore]

Fix looks nice - only bit that seems suspicious is the check for

sym == null

The symbol could be different than null, but still not be a 'valid' 
symbol (i.e. because it's an error). Actually, a lookup should never 
return a null symbol. I suggest you return the 'bestSoFar' (which would 
be typeNotFound') and then use the useful method Symbol.exists() which 
should do what you need (check if the symbol is a valid symbol). I think 
in cases where the found symbol is inaccessible it's important to stop 
and to log the error, you should not keep going recursively until you 
find a correct symbol.
