/**
*
* Support services related to proxy generation and serialization which are required to be implemented by all containers.
*
*
* These services are used by all Weld proxy classes to ensure the correct class loaders are used and to aid in the
* serialization and deserialization of these classes across container instances.
*
*
* Required in all environments since proxies are always in use. A default implementation will be used if none are provided by
* the container which will use the information directly from the type of proxy.
*
*
* {@link ProxyServices} is a per-deployment service.
