One could very well argue that an optional non-greedy dependency is completely
useless and doesn't fulfill any other
purpose but documentation.
We have a bunch of bundles in place that have optional non-greedy
dependencies to allow flexibility at runtime. For example, Logback can
be configured via API, XML or Groovy. Groovy as well as XML
configuration require additional dependencies. Imaging all those
dependencies were greedy.
Then they would be installed of course. Now they are not installed and the dependencies have no purpose aside from what
I mentioned earlier, documentation.
BTW, they need to be optional for the bundles to properly resolve if the
dependencies aren't there. They need to be declared to allow the bundle
class loader to load them if they are available.
To my knowledge, the bundle class loader is using the MANIFEST.MF, not the p2
meta-data. So my argument still stands.
