Misleading compile error - regression

[Sven Reimers]

Hi all,

using a compiler from 9, 10, 11 the following code

package issue;
public class A {

    public static interface I {
        public void m(String s);
    }

    public void add (I i) {}

    public static void main(String[] args) {
        A a = new A();
        a.add(() -> {});
    }
}

results in

... issue/A.java:2: error: incompatible types: incompatible parameter types
in lambda expression
public class A {
Note: Some messages have been simplified; recompile with -Xdiags:verbose to
get full output
1 error

With -Xdiags:verbose the message is correct

... issue/A.java:12: error: method add in class A cannot be applied to
given types;
        a.add(() -> {});
  required: I
  found: ()->{ }
  reason: argument mismatch; incompatible parameter types in lambda
expression
1 error

-> Look at the difference in the line number.

Using JDK 8 everything works as expected (correct line number without
-Xdiags:verbose).

I assume this is not the desired behavior.

Is this already known? Any issue in JBS already?

Thanks

Sven
