Resolve 'sourcecontrol' location URIs in non-Jazz Eclipse plugins

I'm trying to sort out a problem for a client who uses our Eclipse plugins alongside Jazz/RTC. 

As part of our project builder we create a java.net.URLClassLoader configured with an entry for each of the classpath roots visible to the project containing the resource being built. These URLs might refer to a folder i.e. for a referenced source folder or a file e.g. a jar.

When the project under build references another project we convert the source folders of the referenced project to URLs by combining the project location with the relative path of the source folder:

IJavaProject javaProject = ... 

IClasspathEntry entry = ...

IFile file = javaProject.getProject(). getFile(entry.getPath(). removeFirstSegments(1));
URL url = new URL(file.getLocationURI( ).toURL().toString()+"/");

Our ultimate aim is to consume resources under classpath entries as InputStreams. Can anyone help with a way to resolve such resources when they are in Jazz/RTC projects? We are thinking along the lines of either a Jazz-specific URIHandler to process the sourcecontrol URIs, a conversion strategy into a file system path (I expect this is probably not possible in general) or some other API we can use as an alternative to the URLClassloader approach.
