hi all,
 i post my question here even if it does not concern 100% EJB3.

i refer to this post in the jboss-seam forum

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=83706


i have downloaded from cvs latest jboss seam, and i am writing unit tests
using embeddable-alpha6 classes that comes with seam.
whenever i run my tests, i get following exception (here' sstakctrace)
