In the following example, serializing a lambda and reading it back in succeeds on JDK 19 and fails on JDK 20.

I think the culprit is JDK-8059632.

```
import java.io.InputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.OutputStream;
import java.io.Serializable;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.Arrays;
import java.util.function.Predicate;

@SuppressWarnings("unchecked")
public class T {

  enum E {
    ONE,
    TWO,
    THREE
  }

  public static void main(String[] args) throws Exception {
    E e = E.ONE;
    Predicate<E> p = (Serializable & Predicate<E>) e::equals;
    try (OutputStream os = Files.newOutputStream(Paths.get("o"));
        ObjectOutputStream oos = new ObjectOutputStream(os)) {
      oos.writeObject(p);
    }
    try (InputStream is = Files.newInputStream(Paths.get("o"));
        ObjectInputStream ois = new ObjectInputStream(is)) {
      p = (Predicate<E>) ois.readObject();
    }
    Arrays.stream(E.values()).filter(p).forEachOrdered(System.err::println);
  }
}
```
