<p dir="ltr">Hi</p>
<p dir="ltr">+1 to clarify it. All normal scope dont need Serializable constraint - even session scope - and it makes sense to not respect it in a lot of apps without preventing these beans to be serializable thans their proxies.</p>
<p dir="ltr">Best IMO is to either remove it or to allow a scope serializer service to be specified to keep it portable.</p>
<p dir="ltr">Wdyt?</p>
