The bundle, as provided by OBR, has a location of "obr://[bundle

No, there is no way of determining it other than knowing the bundle cache
format of the framework and calculating it yourself.
That's ok - I know we are using Felix. And this worked before I used OBR,
because bundle.getLocation would return a file URL. However the OBR URL
returned by getLocation is totally abstracted. How might I find the
location in the bundle cache?
Just to be clear, we are talking about two different locations:
1. The bundle.getLocation() method was returning the original location
from which the framework made a copy of the bundle to install into
its bundle cache.
2. The bundle in the bundle cache is the copy made from the original
location above.
So, in your old solution you were getting it from the source. Now you
will be getting it from the copy.
Other than explicitly finding it on the filesystem - new
File("felix-cache") and going through the bundle.infos... or is that what
you meant? If so, this might be a show-stopper unless I can think of some
other way.
Well, you can configure the location of the bundle cache using the
org.osgi.framework.storage property, so you can look up this property.
After that, then yes you'll need to know the structure of the cache to
find the bundle you want. You shouldn't need to read any of the files,
though, you just need to know the structure so you can find what you want.
Still sucks, I know, but this is a pretty crappy thing to do in the
first place. ;-)
Some frameworks (hint: Equinox) provide some utility to do this, but we
never have. You could hide all of this behind some method, but it is
still ugly...
