jasm fails to parse a Dynamic constant correctly when the constant has no static arguments but is, itself, nested in a static argument list. I think a "," immediately following the Dynamic constant's name and type should indicate that the static argument list is empty.

The workaround is to use "{}" to indicate an empty static argument list. jdis does not use this workaround, so generates code that isn't properly parsed by jasm.

Original jasm source:

    public static Method constantFilled3I:"()[I" stack 1 {
         invokedynamic
            InvokeDynamic REF_invokeStatic:java/lang/runtime/ArrayCreation.constantFilled
                :"(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/reflect/RuntimeType;IILjava/lang/Object;)Ljava/lang/invoke/CallSite;"
                :_:"()[I"
                {
                    Dynamic REF_invokeStatic:java/lang/invoke/ConstantBootstraps.primitiveClass
                        :"(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/Class;)Ljava/lang/Class;"
                        :I:"Ljava/lang/Class;" {},
                    int 0, int 3, int -3
                };
         areturn;
     }

Note the use of "{}" to indicate an empty list of static arguments to the Dynamic constant.

Run through jasm and then jdis:

  public static Method constantFilled3I:"()[I"
    stack 1 locals 0
  {
         invokedynamic InvokeDynamic REF_invokeStatic:Method java/lang/runtime/ArrayCreation.constantFilled:
                           "(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/reflect/RuntimeType;IILjava/lang/Object;)Ljava/lang/invoke/CallSite;":
                           _:"()[I" {
                             Dynamic REF_invokeStatic:Method java/lang/invoke/ConstantBootstraps.primitiveClass:"(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/Class;)Ljava/lang/Class;":I:"Ljava/lang/Class;",
                             int 0,
                             int 3,
                             int -3
                           };
         areturn;
  }

Same code, but the "{}" has been removed.

Run through jasm and then jdis again:

  public static Method constantFilled3I:"()[I"
    stack 1 locals 0
  {
         invokedynamic InvokeDynamic REF_invokeStatic:Method java/lang/runtime/ArrayCreation.constantFilled:
                           "(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/reflect/RuntimeType;IILjava/lang/Object;)Ljava/lang/invoke/CallSite;":
                           _:"()[I" {
                             Dynamic REF_invokeStatic:Method java/lang/invoke/ConstantBootstraps.primitiveClass:"(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/Class;)Ljava/lang/Class;":I:"Ljava/lang/Class;" {
                               int 0,
                               int 3,
                               int -3
                             }
                           };
         areturn;
  }

Now the trailing arguments have been applied to the Dynamic constant, not the InvokeDynamic constant.
