	* type of the stack item).</li>
	* <li>{@link Opcodes#F_APPEND} representing frame with current locals are
	* the same as the locals in the previous frame, except that additional
	* locals are defined (<code>nLocal</code> is 1, 2 or 3 and
	* <code>local</code> elements contains values representing added types).</li>
	* <li>{@link Opcodes#F_CHOP} representing frame with current locals are the
