What's the reason those are package-protected ctors? Perhaps you can extract some (abstract) super classes from those who access those pckg-prot ctors / methods and place them in the spi pckg. Or all of them can be spi, and only have proper api to expose them - via some factory. The bottom point is that there is no magic bullet. Only common sense and logic. :-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249794#...
