Hi,

I'm migrating my project from jboss6 to jboss7 and have a problem with my Servlet that throws an java.lang.IllegalStateException: The servlet or filters that are being used by this request do not support async operation when i call startAsync.

Step by step i manage to isolate the problem that seems to due to seam-solder presence in my ear/lib folder.
I don't know of it is a seam or jboss bug so i post it on both : http://community.jboss.org/thread/170070

As it works perfectly on jboss AS6 i think it's more a jboss problem but maybe someone here can help.

Best regards,

Maximilien
