Creating class using ASM

at beginning i was planning to create easy class, something like :
class myClass{
public static void main(String arg[])
{
System.out.println(1);
}
}

based on tutorial what i founded i wrote  code:
ClassWriter cw = new ClassWriter(0);
cw.visit(Opcodes.V1_6, Opcodes.ACC_PUBLIC +Opcodes.ACC_SUPER,
		    "myClass",	  // class name
		    null,
		    "java/lang/Object",
		    null);   // source file

MethodVisitor mvc = cw.visitMethod(Opcodes.ACC_PUBLIC, "<init>", "()V", null,
null);
mvc.visitVarInsn    (Opcodes.ALOAD, 0);
mvc.visitMethodInsn (Opcodes.INVOKESPECIAL, "java/lang/Object", "<init>",
"()V");
		mvc.visitInsn	    (Opcodes.RETURN);
		mvc.visitEnd();
		
MethodVisitor mv = cw.visitMethod( Opcodes.ACC_PUBLIC+Opcodes.ACC_STATIC, 
		    "main",		   // method name
		    "(Ljava/lang/String[];)V", // method descriptor
		    null,		     // exceptions
		    null);		     // method attributes
mv.visitCode();
mv.visitFieldInsn  (Opcodes.GETSTATIC, "java/lang/System", "out",
"Ljava/io/PrintStream;");
mv.visitInsn(Opcodes.ICONST_1);
mv.visitMethodInsn (Opcodes.INVOKEVIRTUAL, "java/io/PrintStream", "println",
"(I)V");
mv.visitInsn	   (Opcodes.RETURN);
mv.visitEnd();
cw.visitEnd();
byte[] bytecode = cw.toByteArray();

which is not working, but after i disasseble both classes, i got almost same
code for both of them:
public class myClass extends java.lang.Object{

public myClass();
  Code:
   0:	aload_0
   1:	invokespecial	#8; //Method java/lang/Object."<init>":()V
   4:	return
public static void main(java.lang.String[]);
  Code:
   0:	getstatic	#16; //Field java/lang/System.out:Ljava/io/PrintStream;
   3:	iconst_1
   4:	invokevirtual	#22; //Method java/io/PrintStream.println:(I)V
   7:	return
}

where in my class made from source i have #1 #2 #3 instead of #8 #16 #22

and error message when i'm trying run my class is:
Arguments can't fit into locals in class file myClass
can anyone tell me what i'm doing wrong
regards
