Recent changes to lambda code generation affected how the lambda in the following example captures state, and result in a lambda that was serializable no longer being serializable.

```
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.util.function.Supplier;

public class X {

  public static void main(String[] args) throws IOException {
    F f = new X().f(42).get();
    var baos = new ByteArrayOutputStream();
    try (var oos = new ObjectOutputStream(baos)) {
      oos.writeObject(f);
    }
    System.err.println(baos.toByteArray().length);
  }

  interface F extends Runnable, Serializable {}

  Supplier<F> f(int x) {
    return new Supplier<F>() {
      @Override
      public F get() {
        return () -> System.err.println(x);
      }
    };
  }
}
```

Before:

$ javap -v -p `X$1`
...
  public X$F get();
    descriptor: ()LX$F;
    flags: (0x0001) ACC_PUBLIC
    Code:
      stack=1, locals=1, args_size=1
         0: aload_0
         1: getfield #1 // Field val$x:I
         4: invokedynamic #13, 0 // InvokeDynamic #0:run:(I)LX$F;
         9: areturn
      LineNumberTable:
        line 21: 0


After:

$ javap -v -p `X$1`
...
  public X$F get();
    descriptor: ()LX$F;
    flags: (0x0001) ACC_PUBLIC
    Code:

         1: invokedynamic #13, 0 // InvokeDynamic #0:run:(LX$1;)LX$F;
         6: areturn
      LineNumberTable:
        line 21: 0
