ServiceFactory is not exported

[piemmm]

Hi!

In Services, to register a service, you need to pass in a ServiceFactory which resides in package com.gluonhq.attach.util.impl

• but that's not exported in the module, so nobody can register services (like I need to for map tile storage)

So in com.gluonhq.attach.util.Services you can't call 'registerServiceFactory(ServiceFactory)'

This is in JDK18 (where module-info.java is required).

Can you fix this please?
