> There is a bad bottleneck in Jackson deserialization of {{Bytecode}}. It
> doesn't become extremely apparent until higher levels of load are reached and
> I think is even more evident after the latest bump in Jackson version where a
> bug fix in Jackson itself changed the way in which deserialization caching
> for collections was handled. {{Bytecode}} deserialization was relying on the
> standard Jackson collection deserializers and it costs quite considerably in
> terms of synchronized access to the deserializer cache and to the reflection
> calls required to sort out types.
