<h1>const-class</h1>
<h2>Purpose</h2>
<p>
Move a reference to the class specified by the given index into the specified
register. In the case where the indicated type is primitive, this will store a
reference to the primitive type's degenerate class.
</p>

<h2>Constraints</h2>
<ul>
<li>
A must be a valid register index in the current stack frame.
</li>
<li>
B must be a valid index into the type constant pool.
</li>
</ul>
<h2>Behavior</h2>
<ul>
<li>
An attempt is made to get a reference to the class C the name of which is
contained in type pool entry B.
</li>
<li>
If B refers to a primitive type, the corresponding degenerate class is used
instead.
</li>
<li>
If C has not been loaded and resolved before, it is being loaded and
resolved. All exceptions that are possible during class loading can occur at
this point.
</li>
<li>
A reference to C is moved into register vA, that is, vA' = C.
</li>
<li>
If v(A-1) is the lower half of a register pair, v(A-1)' becomes undefined.
</li>
<li>
If v(A+1) is the upper half of a register pair, v(A+1)' becomes undefined.
</li>
</ul>
<h2>Exceptions</h2>
<ul>
<li>
ClassNotFoundException is thrown if the class does not exist at all.
</li>
<li>
VerifyError is thrown if the class does exist, but could not be verified.
</li>
</ul>
