Looks like the second argument for metafactory is null instead of {{java/lang/CharSequence.length\:()I}}

> After upgrading to 3.0.7, using {{interfaceField::method}} is resulting in bytecode output containing an InterfaceMethodref that looks as expected. When running it in the Eclipse JUnit runner, however (which I think is unimportant), I'm getting a loading error from the JVM:
> {code}
> Caused by: java.lang.ClassFormatError: Invalid constant pool index 130 in class file com/example/sendgrid/SendgridMailSender (not a method)
> {code}
> where the offending constant is
> {code}
>   #130 = InterfaceMethodref #126.#129     // com/sendgrid/SendGridAPI.api:(Lcom/sendgrid/Request;)Lcom/sendgrid/Response;
> {code}
> from the 4.6.8 SendGrid SDK.
> Compiling with 3.0.6 seems to work. Replacing {{::}} with {{.&}} seems to work.
> The JVM is 11.0.9-hs-adpt.
