It's ok for me, in this case.

But did you ever wander why NPE is so common? Isn't that because
people do not want write so much if-s and declare so many one time
used variables.

but ?: can give something nice:
   void f(Some some){
      ( some.getOut ?: defOut ).write(...);
      ...
   }

while ?= would require to:
   void f(Some some){
     OutputStream out ?= some.getOut : defOut;
     out.write(...);
     // Now we need worry for 'out' till end of function.
     ...
   }
