intelliJ IDEA "Overrides method" warning with Java 8 lambda expressions : <p>I get a warning "Overrides method in java.util.function.Function" when using lambda expressions like 
<code>new Vector&lt;String&gt;().stream().map(String::toString);</code> 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?</p>

<p>I use intelliJ IDEA 2016.1.3 with OpenJDK 8 on Gnome on Arch Linux.</p>
