Ok, so after a quick break to watch the football...

I've implemented a compiler for iajc, but I've only tested with an old version of AspectJ, this has one 
major problem:

Old versions (ajc) require that aspect source files be called foo.aj, not foo.java.  New versions of AspectJ 
compiler (iajc) don't have this deficiency.  To get it working with the old (ajc) I replaced the 
GlobPatternMapper with a RegexpPatternMapper so that it could pull in *.aj and *.java files.  I'm now 
going to download the newer compiler (iajc) and rename my files, revert the RegexpPatternMapper to 
the GlobPatternMapper and see if this works.

Apart from this problem (which should be resolved with the newer compiler), all the changes will be 
local to taskdefs.compilers.

Obviously this implementation hasn't been thoroughly tested, and as yet I've only got a barebones 
(compile, no fancy debug options etc) implemetation completed.

Pros:
- enables compilation of AspectJ code within Ant without having to use an external taskdef
- iajc is based on the eclipse compiler and will happily compile 'normal' Java code along with aspects
- minimal impact on the codebase (one change to CompilerAdapterFactory, and a new Iajc class)

Cons:
- still requires aspectjtools.jar on the classpath for the target eg:

  <classpath>
            <pathelement location="${ajlibs}/aspectjtools.jar"/>
            <pathelement location="${build}"/>
  </classpath>

Again sorry for using Bugzilla for this, but my ISP is still not happy.
Kev
