I'm fine with separate types.

You re-throwing any of the exceptions wrapped into `RuntimeException`. From this point of view, a single `Exception` won't change anything: if an exception is thrown, it's caught and re-thrown. These four exceptions are the only checked exceptions that can be thrown, catching `Exception` will catch them either way.

Either way is fine with me.
