Invokedynamic instructions don't get line number table entries

Consider this small program:

1: package scratch;
2: public class MainApp {
3: public static void main(String[] args) {
4: Runnable r = () -> {};
5: System.out.println(r.toString());
6: }
7: }

When compiled with javac the resulting file looks like this:

 public static void main(java.lang.String[]);
    descriptor: ([Ljava/lang/String;)V
    flags: ACC_PUBLIC, ACC_STATIC
    Code:
      stack=2, locals=2, args_size=1
         0: invokedynamic #2, 0 // InvokeDynamic #0:run:()Ljava/lang/Runnable;
         5: astore_1
         6: getstatic #3 // Field java/lang/System.out:Ljava/io/PrintStream;
         9: aload_1
        10: invokevirtual #4 // Method java/lang/Object.toString:()Ljava/lang/String;
        13: invokevirtual #5 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
        16: return
      LineNumberTable:
        line 4: 5
        line 5: 6
        line 6: 16

Notice that line 4 begins at bci 5, not on the invokedynamic instruction.

When compiled with the eclipse compiler the file looks like:

  public static void main(java.lang.String[]);
    descriptor: ([Ljava/lang/String;)V
    flags: ACC_PUBLIC, ACC_STATIC
    Code:
      stack=2, locals=2, args_size=1
         0: invokedynamic #19, 0 // InvokeDynamic #0:run:()Ljava/lang/Runnable;
         5: astore_1
         6: getstatic #20 // Field java/lang/System.out:Ljava/io/PrintStream;
         9: aload_1
        10: invokevirtual #26 // Method java/lang/Object.toString:()Ljava/lang/String;
        13: invokevirtual #30 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
        16: return
      LineNumberTable:
        line 4: 0
        line 5: 6
        line 6: 16
      LocalVariableTable:
        Start Length Slot Name Signature
            0 17 0 args [Ljava/lang/String;
            6 11 1 r Ljava/lang/Runnable;

Notice that line 4 begins at the bci 0.

I don't know which variant is right, but they differ. The problem is when debugging and setting a breakpoint on line 4, should the invokedynamic be executed before the breakpoint happens or not?
