javac may crash on a record pattern with too few components

Consider code like:
---
public class Err {

    record R(String x) {}

    public void(Object obj) {

        switch(obj) {

            case R(var v, ) -> 1;

        }

    }

}
---

javac may crash on this code:
---
$ ./build/linux-x86_64-server-release/images/jdk/bin/javac -XDdev -XDshould-stop.at=FLOW /tmp/Err.java
