Throw a specialized exception when BeanManagerAware cannot resolve BeanManager
------------------------------------------------------------------------------

                 Key: SOLDER-50
                 URL: https://issues.jboss.org/browse/SOLDER-50
             Project: Seam Solder
          Issue Type: Feature Request
          Components: Core
            Reporter: Dan Allen
            Assignee: Lincoln Baxter III
            Priority: Minor


The BeanManagerAware#getBeanManager() method currently throws an IllegalArgumentException when the BeanManager cannot be found by any provider. Because this exception is so generic, it's dangerous to bundle the lookup with other code because you aren't sure whether the IllegalArgumentException came from the BeanManager lookup or from a subsequent call, as in:

try {
   BeanManager beanManager = BeanManagerAccessor.getBeanManager();
   beanManager.fireEvent(payload);
}
catch (IllegalArgumentException e) {
   // what caused this?
}

Introduce a specialized checked exception for this unique failure. The proposed name is BeanManagerNotAvailable (or BeanManagerNotFound)
