> David Bosschaert some time ago contributed a set of Equinox Aspects-based
> examples showing how to use aspects to make SPI work inside an OSGi
> container. I promised to contributed an enhanced verion of these mechanisms
> and integrate these into SPI-Fly /Maven projects, Pax Exam, etc./. I'll
> attach a patch with those changes in a moment.
> Few important notes:
> 1. This not intended to be committed directly to Aries SVN. The only purpose
> of this patch is to provide initial impl that could be used when doing
> additional experiments and evaluation. The patch is dirty, I was in hurry
> when doing it and there are lots of ugly pieces of code inside :). If we
> decide to go with this approach, I'll prepare a clean patch once I'm back
> from vacation - in two weeks' time.
> 2. The problems that were identified in the discussion about using AspectJ in
> SPI-Fly haven't been resolved yet. This includes (but is not limited to):
> - being tightly coupled to Equinox; this piece of code is based on Equinox
> Aspects/Weaving; this will not work wit any other container
> - inability to tell AspectJ to run an aspect on behalf of other bundle; each
> bundle that wants to use these new features, needs to contain an aspect and
> other settings like a Require-Bundle header
> 3. This patch introduces a SPI-Consumer header and enhances the SPI-Provider
> header. A Pax Exam test show how to use this new functionality once you copy
> the aspect to your bundle and configure Require-Bundle header.
> 4. I haven't found the latest version of Equinox Weaving in any of publicly
> available Maven repos. That is why, these libraries will need to be copied
> manually to the itests project (to the weaverBundles subdirectory). I'll
> attach these bundles to this JIRA.
> This patch is huge, so I guess there might some issues with applying it. If
> you have problems with that, let me know and I'll try to generate it again.
