> In RpcEngine,
> {code}
> VersionedProtocol getProxy(Class<? extends VersionedProtocol> protocol, ...)
> {code}
> should be
> {code}
> <T extends VersionedProtocol> T getProxy(Class<T> protocol, ...)

> Also, while removing casts I encountered a bug of the method
> HConnectionManager.HConnectionImplementation.getProtocol() using broken logic
> just like double-checked locking for HashMap.
