  static final void test(Deque<Integer> p1, Supplier<Integer> p2) {
    Supplier<Integer> x = (true) ? p1::peek : p2;
    
  }
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 8: [Static type checking] - Cannot assign value of type 
java.lang.Object to variable of type 
java.util.function.Supplier<java.lang.Integer>
 @ line 8, column 27.
       Supplier<Integer> x = (true) ? p1::peek : p2;
                             ^

1 error
{code}

Compile successfully
