NOTE: THE FOLLOWING TEXT EXTRACTED FROM JVMS7.PDF
<p>
The Deprecated attribute is an optional fixed-length attribute in the attributes
table of a ClassFile, field_info or method_info structure.
A class, interface, method, or field may be marked using a Deprecated attribute to
indicate that the class, interface, method, or field has been superseded.

A runtime interpreter or tool that reads the class file format, such as a compiler,
can use this marking to advise the user that a superceded class, interface, method,
or field is being referred to. The presence of a Deprecated attribute does not alter
the semantics of a class or interface.

The Deprecated attribute has the following format:
<pre>
	Deprecated_attribute {
		u2 attribute_name_index;
		u4 attribute_length;
	}
</pre>
