Thought I should explain more:
fragment_1 and bundle_b are both 3rd party jars which I osgified. The
reason that fragment_1 is attached to bundle_a is that code in bundle_b
uses the context class loader which is associated with bundle_a and i need
it to find resources in fragment_1.
bundle_a is also 3rd party.
so in terms of changing code i have very little I can do. I'm looking for
a solution by using manifest file declarations (or maybe it is an equinox
bug that it doesn't detect that there are 2 bundles providing the same
package?)
