Java 7 String switch decompiled: unexpected instruction

I have decompiled a very simple class that uses the new Java 7 String Switch feature.

The class:

public class StringSwitch {

    public static void main(String[] args) {

        final String color = "red";
        switch (color) {
            case "red":
                System.out.println("IS RED!");
                break;
            case "black":
                System.out.println("IS BLACK");
                break;
            case "blue":
                System.out.println("IS BLUE");
                break;
            case "green":
                System.out.println("IS GREEN");
                break;
        }

    }

}

Running the Java 7 "javap" against this class, generates an interesting set of instructions (the complete disassembled code is available here):

public static void main(java.lang.String[]);
    flags: ACC_PUBLIC, ACC_STATIC

    Code:
      stack=2, locals=4, args_size=1
        ...
        12: lookupswitch  { // 4

                  112785: 56

                 3027034: 84

                93818879: 70

                98619139: 98
                 default: 109
            }
        56: aload_2       
        57: ldc           #2                  // String red
        ...       
       110: tableswitch   { // 0 to 3

                       0: 140

                       1: 151

                       2: 162

                       3: 173
                 default: 181
            }
       140: getstatic     #8                  // Field java/lang/System.out:Ljava/io/PrintStream;
       143: ldc           #9                  // String IS RED!
       ...
       181: return

The "LOOKUPSWITCH" is an instruction used when the switch case is sparse and can replace the TABLESWITCH, that is the default instruction for "switch" statements.

So, the question is, why are we seeing a "LOOKUPSWITCH" followed by a "TABLESWITCH"?
