Redundant 'isInstance()' or 'cast()' call

Reports redundant calls of java.lang.Class methods.

For example, Xyz.class.isInstance(object) can be replaced with object instanceof Xyz. The instanceof check is preferred: even though the performance will probably be the same as these methods are intrinsics, they better indicate a static check.
