Well, given that bundleresource is an org.eclipse.core thing, I'm not
sure that the dependency on it is unreasonable. Obviously there's
nothing in standard JVM/JDK classes that knows how to convert
bundleresource://9/./ into D:/path_to_plugin, so you're already going
to need help.
Nick illustrated the other issues with using normal File APIs for
URLs. It may be that we can add more URL-aware behaviors into File/Dir
or we may consider writing a small URL library that acts like
IO/File/Dir instead.
