The earlier creation of a specific property called keepSessions for
http sessions on web apps implied (to me) that someone thought it made
sense to specifically identify the container type of interest for
turning this on or off. Oherwise why not just have the property
keepState or introduce a keepState option?
Perhaps I assumed wrong.
Anyway, I certainly don't have a specific use case in mind for
retaining some but not all types of state. I do worry some about the
point Vince raised - as soon as we prevent it, someone will want it.
His suggestion for allowing
--keepState (which means "all")
and
--keepState=web,ejb,...
covers all bases. As I and several others have pointed out we'd
continue to support --property=keepSessions=true for backward
compatibility.
It's a separate question, as Ludo raises, whether a developer using an
IDE wants to see a toggle for each container type. If the IDE use
case is to retain all or nothing then there is just the single
toggle: keep or not. Right?
