<p>There is also a bug in that the compiler should not be calling arbitrary equals methods at compile time.  I haven't had a chance to dig into the code yet, but what probably should be happening is that the compiler should check to see if there is exactly one equals method that is callable and that it is Object.equals (which is ==).  Only if that is true should the compiler attempt to resolve similar of ObjectConstantOperands to a definitive answer.</p></div>
