[jboss-dev-forums] [Design of EJB 3.0] - metadata-related NPEs: empty collection vs null

[alex.loubyansky@jboss.com]

There is a number of NPEs in EJB3DescriptorHandler currently. The code doesn't expect null as a value of collection-valued metadata properties. I started adding checks for null for now. But it would probably be better to return empty collections?
