How to import java.lang.invoke.LambdaForm;?

Question

Java

Goodness, this language makes my eyes bleed...

there is this line import java.lang.invoke.LambdaForm;

it, as it may seem to many, imports LambdaForm, BUT no, it gives the error "Cannot resolve sybmol "LambdaForm""

What and where should I import in order for the import to work normally?
Thank you
