> While reviewing the implementation of BeanManagerProvider I saw that getBeanManager() may return null in some rare circumstances. Unfortunately this forces everyone calling this method to check the result for null. I think most code calling the method absolutely requires the BeanManager and cannot proceed without it.
> Therefore it would be nice to have some alternative getBeanManager() method that doesn't return null if the BeanManager is not available but instead throws a meaningful runtime exception. That's what Solder does per default. Calling Solder's BeanManagerLocator.getBeanManager() without a BeanManager being available will result in a BeanManagerUnavailableException.
> The attached patch adds a method getRequiredBeanManager() to the BeanManagerProvider implementing this behavior.
> I'm not sure if this minor thing should be discussed on the mailing list. If you think this should be discussed, please let me know, then I'll start a topic on deltaspike-dev.
