New reflection validation in ReflectionUtils -Pulls up class type checking to before actual class load; fails fast -Add check of array length. -Limit recursive depth to 100. +Sequence file logic. Conf loading does force classloading, so move sequence file logic out of it. This does remove it from the conf file weak hash map of classes, but the jvm does its own class map here. The real feature of the conf map is the caching of cache misses, which would actually surface as errors on reading files, so you aren't saving anything performance-wise.

Validate class instantiation through ObjectWritable and elsewhere to make sure
the class is of the requested type before the class is instantiated
