instanceof pattern inside lambda causes issues.

Using instanceof pattern inside of lambdas breaks multiple features. Examples:

• hovering over elements stops showing the signature
• Renaming from inside the method with the pattern pops an internal error (https://pastebin.com/iTZDjVq0)
• Attempting to Go To Definition of a field or method doesn't work inside the method with the pattern
• Sometime intellisense stops suggesting things

Environment

• Operating System: Windows 10 PRO 1909
• JDK version: Graalvm Java 16 21.1.0
• Visual Studio Code version: 1.59.1(2021-08-19)
• Java extension version: v0.81.0

[Please attach a sample project reproducing the error]

public class Test {
    public static final void bug() {
        Optional.empty().ifPresent(o-> {
            if(o instanceof byte[] array) {
                Object local = null;
            }
        });
    }
}

Additional Informations

Inizia aprendo l’esempio Java fornito in VS Code con la Java extension indicata e riproducendo i malfunzionamenti di hovering, rename, Go To Definition e IntelliSense. Abilita i Java extension logs usando la guida di troubleshooting collegata e confronta il comportamento con i due pastebin collegati. Il lavoro è completato quando queste funzionalità del linguaggio funzionano all’interno del pattern instanceof usato nel lambda.
