/**
 * If a Cougar server response contains a class the client doesn't know about (which is legal and backwards compatible
 * in cases) then the default behavior of Hessian is to perform a lookup, fail, throw an exception and log it.
 * This has been measured at about 25 times slower than the happy path, and Hessian does not negatively cache 'misses',
 * so this is a per-response slowdown. This implementation caches type lookup misses, and so eradicates the problem.
