It thinks the variable could be null when we are checking that it is not null.
Comment 1 Svata Dedic 2015-11-23 19:37:17 UTC
The good news is that the new implemenation handles the situation correctly -- as the loop condition tests the assignment (= the variable value) for != null, the value is asserted to be non-null within loop body.

The bad news is that it the new impl is still a little clumsy and not well tested :-/
