If a factory has been previously set for either the framework fails to
initialize.
I understand that these two calls both have to succeed in order to provide
an OSGi URL Handlers Service (at least in R3).
My question is can Eclipse be modified reasonably to run without these
calls?
In the environment in which I'm running these singleton operations may have
been called already.
I have a working prototype in which I've fixed up a few "reference:" URLs
that were being created from String but to be honest don't know all the
repercussions.
Is "bundleresource:" or "bundleentry:" used to create URLs by string
anywhere?
What is "platform:" used for -- I see it mentioned in the odd bug report --
are there plans for it?
Thanks.

You could probably find a way around the bundle urls.
However the platform urls are APIs and some plugins might construct them
directly and use them to access data.
Therefore you might be able to run but it is unclear how far you could go.
HTH,

Hi Pascal,
Thanks for your reply.
What if the URL creation changes were restricted to just org.eclipse.osgi
and org.eclipse.core.runtime -- I really just want the non-UI basics.
In this way the eclipse core could still initialize without necessarily
calling the singleton operations. I don't believe that externally the API
would be affected.
I'm not sure what might be the best way to control whether the ops get
called but certainly a flag/property would work or perhaps there is a
better way(?)
I'd be pleased to volunteer to do this work (even just for a prototype) if
you think it's feasable/reasonable.
--
You mentioned the platform URL as being API...
Is there a way to create a "platform" URL other than by spec (and the
default URLStreamHandlerFactory)?
Is "reference" also considered API?
