How to solve this issue: I have a Class ref and array of Annotation refs, which together compose my Map key. Since I have no callback hooks for removing this key I need something similar as what WeakHashMap would do if my key was only that Class ref - removing the whole entry when Class ref is GCed. Is there an easier way than rewriting the whole WeakHM (or some similar construct)? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4151986#...
