javac rejects code which is supposed to be compilable

code sample:

import java.util.function.Function;
class Sample {
   public <T, R> void foo(Function<R, T> f1, Function<T, R> f2, R r) {}

   void m(Integer intValue) {
       foo(o -> o, o -> o , intValue);
   }
}

Error:
C:\\Desktop\\Sample.java:6: error: incompatible types: cannot infer
type-variable(s) T,R
foo(o -> o, o -> o , intValue);
 ^
  (argument mismatch; bad return type in lambda expression
    Object cannot be converted to Integer)
where T,R are type-variables:
  T extends Object declared in method <T,R>foo(Function<R,T>,Function<T,R>,R)
  R extends Object declared in method <T,R>foo(Function<R,T>,Function<T,R>,R)
