The only reason for this is the ClassLoader.getResources() call within the
one of the Sun classes that we use. Probably we can create similar
implementation and use the classloader that created GDSFactory class.

If you want to contribute the code, please check the
sun.misc.Service.providers method.

For JayBird that should be enough.
