    weld-se-core + weld-servlet-core -> interceptor not working

    Ondrej Zizka Master
      Hi all,

      I have a non-typical application, which uses weld-se-core, and one of it's modules uses weld-servlet-core in embedded Jetty 6.

      1) Debugging reveals that BeanManager is initialized twice. Which means, methods like addBeans() are called twice. First when the app boots up, then when Jetty boots, with this call stack:

      ****************

      Is that ok?


      2) I have an intercepted class, @JpaTransactional, which works when used without weld-servlet-core (in other module which does not have weld-servlet-core, and the web module is not on classpath at all).
      When used from a servlet, the interceptor does not work - seems like it's not called at all.

      I think I have it properly configured.
      My suspicion is that the problem is that BeanManager is initialized twice and somehow they don't cooperate. I'm not sure how this should work, but intuitively, I guess only one BeanManager per JVM should exist and should be looked up everywhere it's needed.
