I understand there are factors at play here other than what JDK I used in my previous jobs, but a lot has gone on since JDK 1.4, and I haven't used any of the new 1.5 or 1.6 features in a production environment. Can that hurt me significantly? Almost every tutorial I see uses generics, enums, var args, and the like, and I wonder if I'm really behind the curve.
i would tag this question subjective :-)
