In the particular instance of casting to Class<LinkHandler>, you
probably shouldn't be doing this anyway. If you can refer to the class
lexically from the code, then you should just use a class literal
expression instead of ClassLoader.loadClass to obtain the reference.
However, you might wish to cast the reference to something else, for
example, Class<? extends LinkHandler>, and the problem would still
apply.

It's unfortunately not really possible to develop with generics and
warnings for unchecked casts enabled, without just ignoring certain
compiler warnings.
