Which order do you prefer for null testing ternary expressions? (self.java)

Which do you prefer of these two? The goal is the same. If bar is null then make foo null and avoid the exception. In other languages there is the ?. operator to help with this.

foo = bar == null ? null : bar.baz();
foo = bar != null ? bar.baz() : null;

I ask because I feel like the "English" of the first example is easier to read and has less negations so it is more straightforward, but the second one has the meat of the expression (bar.baz()) more prominently.

This is much less readable if non-trivial. It's easy enough here, but now I need to search through the code to see where else foo was set.
