Quite a few additions to the language. Nothing you can't find in other languages, but when it comes to programming languages that's as close as we come to real progress...

The most useful Java feature for the kind of work I do would be some mechanism that lets you avoid per-object memory overhead. For example, implementing an array of objects as a bunch of parallel arrays, one for each member variable. Or the value object proposals.
Since objects in java currently have 8-12 bytes of overhead (depending on the VM), it restricts my designs pretty severely when designing very large scale systems.
By the way, I wrote up a design for one-byte virtual function pointers, if anybody's interested.

(How'd we get two of these discussions?)

Very few applications require stack allocated objects or one byte overhead for methods. *Some* do. Most don't, although programmers will tend to think that they do, because, hey, the stack is more efficient than the heap, right?

Ehud posted a message at the top level so that those people who only read the front page/the RSS newsfeed could see that there was a thread in the discussion group. It's common practice.
