<p>
Java virtual machine instructions do not rely on the runtime layout of classes,
interfaces, class instances, or arrays. Instead, instructions refer to symbolic
information in the constant_pool table.
<p>
All constant_pool table entries have the following general format:
<pre>
		cp_info {
			u1 tag;
			u1 info[];
		}
</pre>
Each item in the constant_pool table must begin with a 1-byte tag indicating
the kind of cp_info entry. The contents of the info array vary with the value of
tag. The valid tags and their values are listed in Table 4.3. Each tag byte must be
followed by two or more bytes giving information about the specific constant. The
format of the additional information varies with the tag value.
