Sorry, I should have been more specific--I use Eclim to bring gvim inside the Eclipse environment, or I use Netbeans with a set of macros that parallel my vim ones. I find the built-in "boilerplate simplification" nonsense to be a patch over the fact that Java itself is no better than mediocre, and should not be considered a valid defense of Java as a tool.
And the reason? Because even with all these tools that have grown up around Java to address its shortcomings, it completely sucks. Absolutely sucks. Miserable to write and--more importantly--miserable to read. Meanwhile, I can comfortably write idiomatic Scala in Netbeans (the Eclipse plugin is shaky) with the editor's only help being Intellisense, idiomatic Scala that another programmer can read easily without trouble, because the language is geared toward actually being descriptive rather than covered in boilerplate.
And Scala is not a dynamically typed language, but shows that a static language can actually act very similarly to one. And you still get all those features that you miss. It's sort of what you're talking about re: AS3, but it's here now and works.
.
I wasn't joking earlier when I said that the best Java "tool" is a Scala compiler. It's not perfect (hello, long compile times), but I can do anything that I do in Java faster and with more readable and therefore reliable code in Scala. The reverse is not true, because to get around Java's inherent lack of expressivity you are forced to create new points of failure for yourself.
That's not good. It's not necessary. But it's defended to the death by people who--not you, but some of the other posters on this thread--really do truly think in Blub and don't understand why these things are bad.
