Can't rely on target typing when chaining methods [closed]

问题

In Java 8, type inference has been extended to target typing which enables to write:

Comparator<String> ascending = comparingInt(String::length);

without having to use a type witness (Comparator.<String> comparingInt). However the last statement below does not compile. Is there a reason? Is there a workaround?

Comparator<String> ascending = comparingInt(String::length);                //ok
Comparator<String> descending = ascending.reversed();                       //ok
Comparator<String> descending = reverseOrder(comparingInt(String::length)); //ok
Comparator<String> descending = Comparator.<String>comparingInt(String::length)
                                                  .reversed();              //ok
Comparator<String> descending = comparingInt(String::length).reversed();    //error

回答1:

The problem is fixed with build 129 (but appears until build 128).
