[aspectj-dev] AspectJ weaver to 1.5?

[Andy Clement <andrew.clement@xxxxxxxxx>]

The inability to use generics/autoboxing and most importantly of all
covariance is extremely painful when working on the compiler and
weaver.  I'm toying with upgrading the code (as I work on it) to use
these Java 5 features.

I wanted to collect any comments people have?

- how important is it that the compiler/weaver are still usable on Java 1.4?
- does anyone have experience of using something like retroweaver to
create a 1.4 variant of a 1.5 built codebase - does it work ok?

This won't affect the ability to process  back level classes or
produce back level classes, it just means the execution of the
compiler and weaver will require a 1.5 JRE.

cheers,
Andy
