Hi Steve,<br>
<br>
this is not caused by a change in the specification nor in Weld. It
is probably a regression in GlassFish integration. The correct
behavior is the former (2 instances) as that is aligned with how
@Dependent instances work in general. If you need the bean instance
to be shared across injection points, you can give it a scope other
than @Dependent.<br>

<p class="MsoNormal">We are investigating a change in behaviour
between Java EE 6 and Java EE 7 and were wondering if this is
a bug or a specification change;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If there is a RequestScoped bean and SFSB
like below, and I call invokeStatefulService() on the Request
Scoped Bean the behaviour changes depending on Java EE
version;<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">On GFv3 and JBoss EAP 6 the method returns
"init" implying we have 2 separate SFSB instances.<o:p></o:p></p>
<p class="MsoNormal">and on GFv4 and WildFly the method returns
"stateFromFirst" implying there is 1 SFSB instance.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would’ve imagined that the second result
i.e. 1 SFSB as there is 1 client bean which exists for the
duration of the call is the correct behaviour. However I am
not sure.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As both appservers above use JBoss Weld for
CDI is this a Weld bug or did the behaviour change between
Java EE 6 and Java EE 7?<o:p></o:p></p>
