<HTML><BODY>Hi all<br><br>The question is about using Pax-Web (osgi servlet container) + Pax-Cdi + Weld.<br>There is a bug in pax-web <a href="https://ops4j1.jira.com/browse/PAXWEB-760">https://ops4j1.jira.com/browse/PAXWEB-760</a> than can't<br>be fixed about 2.5 year. And it seems that it is linked with weld. So I post<br>my question here - maybe someone of weld developers can give any hints, ideas<br>etc that can help us. So, the situation.<br><br>Configuration: jetty 9.3.11.v20160721, weld 2.2.12.Final, pax-cdi 0.13.0-SNAPSHOT, <br>pax-swissbox 1.8.0 , pax-web 6.0.0-SNAPSHOT.We must have a war bundle with <br>servlet + cdi bean. In servlet we do<div class="code panel" style="border-width: 1px;" data-mce-style="border-width: 1px;"><div class="codeContent panelContent"><pre class="code-java"><span class="code-keyword">private</span> void processRequest(HttpServletRequest request, HttpServletResponse response){
HttpSession session = request.getSession();
session.setMaxInactiveInterval(60);<span class="code-comment">//Note, these are seconds.
</span> ....call some cdi bean method
}
</pre></div></div><p>The problem appears when we update war bundle on osgi when there is a live session. <br>So, timing is very important here. What we do by steps and time:<br> hr:min:sec<br> 1) at 00:00:00 we start our war bundle<br> 2) at 00:00:10 we make the first http request to our servlet with cdi bean call<br> 3) at 00:00:30 we update our war bundle on osgi (Bundle.update)<br> 4) at 00:00:40 we make the second http request to our servlet with cdi bean call<br> 5) at 00:01:40 we get the following exception:</p><div class="code panel" style="border-width: 1px;" data-mce-style="border-width: 1px;"><div class="codeContent panelContent"><pre class="code-java">2016-08-28 16:40:53,385 | WARN | er@57af3ea4Timer | 39 - org.ops4j.pax.web.pax-web-jetty - 6.0.0.SNAPSHOT | org.ops4j.pax.web.service.jetty.internal.LateInvalidatingHashSessionManager | Problem scavenging sessions
