A DESCRIPTION OF THE PROBLEM :
When having a generic typed argument, specified to be a subclass via extends, I cannot access member method from this type. For example, in "<C extends Field> void test(C field)", I cannot access fields member methods

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
try to compile the attached source code

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect the code to compile successfully, like it does with ECJ, since there isn't any ambiguous references or something.
ACTUAL -
The code does not compile. The compiler

Test.java:10: error: invalid method reference
        Consumer<String> setter = field::setValue;
                                  ^
  cannot find symbol
    symbol: method setValue(String)
    location: bound of type variable C
  where C is a type-variable:
    C extends Field declared in method <C>test(C)
1 error


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.function.Consumer;
 
class Field {
    void setValue(String t) {}
}
 
class Test {
    protected <C extends Field> void test(C field) {
        Consumer<String> setter = field::setValue;
    }
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
One simple work around would be assigning the generic variable to a new, not generic variable first:

--------
  Field f = field;
  Consumer<String> setter = f::setValue;
--------

or using a lambda instead of a method reference:

--------
  Consumer<String> setter = val -> field.setValue(val);
--------
