RE: [aspectwerkz-user] A couple of questions

Thanks for the reply Alex,

We are using AW2.0

We don't mind trying CVS head but if there is no official release due then
we may be better spending time migrating to AJ5..
is M4 yet feature complete (Im not sure if that's what you mean in ur
reply)?

When is AJ5 final scheduled for release?

-neil.

Hi

As you know we merged AspectWerkz technology with AspectJ to produce
"AspectJ 5". This explains the low activity after we shipped the fairly
stable AW 2.0.

AspectJ 5 is in M4 state, and we will do one RC1 more before it gets final,
beeing feature complete with what AspectWerkz syntax brings. I 'll write a
tech. paper to deeply describe the delta / migration path in this timeline
as well.

That said, which version of AW are you using? Is it 2.0 or chs head. CVS
head has changed a lot since 2.0 as I'have been f.e. doing ASM 2.0 upgrade,
backport175 integration, and rearchitected the AspectOf and MixinOf backend
- which indeed as been a weakness so far. As I did not had time (working on
AspectJ 5 integration) and as noone really asked for I never shipped an
official AW 2.1.

I can certainly spend time in a fix for you but :
- what are the chance for you to migrate to AJ 5 final ?
- can you provide me a test case that spot a problem for AW 2.0 (assuming
you are using it)
- can you try with AW-latest by building cvs head ? If the bug is not there
anymore, are you comfortable with using that version?
- can you find a workaround instead?

As you understand, unless there is a high demand for a AW 2.1 I will
certainly encourage everyone to migrate to AspectJ 5 - especially when it
will be final. Alex
