intelliJ IDEA "Overrides method" warning with Java 8 lambda expressions

Question

I get a warning "Overrides method in java.util.function.Function" when using lambda expressions like new Vector<String>().stream().map(String::toString); but as far as I know this is just normal lambda usage. How can I get rid of this warning without removing legitimate override warnings?

I use intelliJ IDEA 2016.1.3 with OpenJDK 8 on Gnome on Arch Linux.

Do you mean the icon in the editor gutter? That is not a warning, but an indication and allows navigation to the super method using the mouse. The icon(s) can be disabled in File | Settings | Editor | General | Gutter Icons.
