> We ran into a problem today debugging some class loading problem during
> deserialization, and JVM was masking the underlying exception which made it
> very difficult to debug.
> We can however log the exceptions using try/catch ourselves in
> serialization/deserialization. The good thing is that all these methods are
> already using Utils.tryOrIOException, so we can just put the try catch and
> logging in a single place.
