Diamond operator no longer working... ?

[assembling signals]

Hello, community!

I noticed a new error since b134: "Cannot use '<>' with anonymous inner 
classes".
The code uses diamond syntax and was error-free before b134.
(Please see reproducible example at the end.)

Can someone explain: is this error even intended?
If so, why this is necessary? If not, is it possible to revert to old behavior?

(BTW: Latest Netbeans even allow to refactor anon-inner-classes to use diamond 
syntax.)

Best regards,
Ivan G Shevchenko

                                return false;
                        }

                        @Override

                                return null;
                        }

                        @Override
                        public void remove() {
                                throw new UnsupportedOperationException();
                        }

                };
