1. in 'Tools-->Options-->Hints-->General', make sure 'Assignment To Itself' is checked
2! create class 'Foo' with this code:

public class Foo
{
    private String name;
    private int value;
    
    public Foo(String name, int value)
    {
        this.name = name;
        this.value = value;
    }
    
    public void copy(Foo foo)
    {
        this.name = foo.name;
        this.value = foo.value;
    }
}

the two lines in the 'copy' method are incorrectly highlighted.

Also, capitalization in the 'General' hints option is very inconsistent.
