Use member reference hint does not work when invoked for static method

Steps to reproduce:
1) have a class:
public class Test  {
    public static void neco() {        
    }            
    public void akce() {
        Runnable r = () -> {
            neco();
        };       
    }    
}

2) in lambda body apply hint "Use member reference"
-> the method is changed to:

    public void akce() {
        Runnable r = this::neco;       
    }

but expected is 

    public void akce() {
        Runnable r = Test::neco;       
    }
