Re: [aspectwerkz-user] A couple of questions

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.
