</blockquote>By the way, regarding the latter sentence in the above quoted text - that would mean you can basically never be sure whether a long-running conversation is alive. Weld does not follow this bit either and does not destroy your conversations in such unexpected manner.

<p style="margin: 10px 0 0 0">1. It says "associated with no current Servlet request", but <tt>session.invalidate</tt> destroys even the current conversation immediately. <br /> 2. In RFC2119 terms this is a MAY statement - it's "permitted". While the session invalidation logic is described matter-of-factly, as a MUST.<br /> 3. I don't think this should be taken to extreme like that, the notion "you can basically never be sure whether a long-running conversation is alive" would mean that there is basically no point in using long-running conversations at all. The permission is quite broad, but I would expect an implementation to be reasonable.</p>
</blockquote>Would you be able to point me towards some realistic scenario where it would make sense to make it work literally as described in the spec?
<blockquote style="margin: 10px 0 0 0; border-left: 1px solid #ccc; color: #707070; margin-left: 19px; padding: 10px 20px"></blockquote><br /> We keep EntityManager in the conversation scope, and transaction handling is tied to JSF phases (ala Seam 2). It's an "Open Session in View" + extension of Fowler's "Unit of Work" thing.<br /> When the conversation is destroyed during logging out, the em gets closed. Transaction handling tries to join the transaction to em and fails, since it's closed.
<p style="margin: 10px 0 0 0">And again, at least for the current conversation how is session invalidation different from an explicit <tt>conversation.end()</tt> call? </p>
