Hi,
I just tried the new Weld 1.1.3.Final release and noticed several ClassNotFoundExceptions on container startup. Weld complains about missing drools and hibernate classes. I don't use database persistence nor transactions, so I don't have hibernate in my classpath (my app is running on Tomcat 6). I'm not sure if this a Seam Faces or Weld issue. I didn't change the Seam Faces jars. The exceptions were not thrown using Weld 1.1.2.Final.
Nevertheless, the web app is deployed and works. Just these exceptions are a bit annoying.

Here the stacktrace:

This is my beans.xml where I disable transactions:

<t:SeSynchronizations>
     <s:modifies />
</t:SeSynchronizations>
<t:UTTransaction>
     <s:modifies />
</t:UTTransaction>
<sc:Veto>
     <s:Qualifier />
</sc:Veto>
<ft:TransactionPhaseListener>
     <s:replaces />
     <sc:Veto />
</ft:TransactionPhaseListener>
 

Thanks for any hints!
