Generics in production code?

Hi all!

As you probably noticed, we - after much debate - plan to support JSR014
"Generics" in Aurora. And you can expect at least the parser in a build or
two :).

However, our motto here is "to eat one's dog food" - that is, we would like
to use Generics in IDEA (and, as a matter of fact, are looking forward to
do so :) ).

The current beta implementation of Generics (version 1.3) can be used "on
top" of JDK 1.4.1 - that is, compile with generics supporting javac, and
run with JDK 1.4.1. You can even enjoy generic collections - a special
generic stubs are provided, against which your code should be compiled. And
we were actually able to compile IDEA with it and use it afterwards :)
(no, the next build is compiled with conventional javac of 1.4.1_something).

However, latest statements from Sun are somewhat vague on the point of
whether this happy state of events will continue past a revised version of
JSR014, due in the end of May. That is, it may well be that code using
Generics will not run on older JVMs.

So, the question is - have you tried to use Generics in production code?
Do you consider doing so before 1.5 is out? If you do so, how are you going
to cope with changes from Sun?

Your comments are very welcome.

Cheers,
Dmitry

We plan to implement another feature - something like "Convert to use of
Generics". It will run on your project (or only selected package/file) and
try to convert it from using non-parametrized collections into
parametrized ones. Would you find it useful?

That would be good - however, I think also having an intention action
would be nice. ( also adding it to the code inspection would be good ).

Now THAT I would DEFINITELY use! Even if it's not right now, but when things do become 'official', then I can use idea to quicly blast me into Generics and go from there. YES! +1

Yes, this is correct. See Draft Spec for more details and answers to whys.

Cool, some people will certainly have fun searching for the cause of
this problem. Maybe you can add a check for that in the Code Inspection
or even a warning in the editor for that. Do you want me to add a
request in the tracker?

I do not think there is a need for separate request, as such warning is
issued by javac, hence we will implement respective highlighting in editor.

Friendly,
