Guillaume Nodet commented on KARAF-3518:
----------------------------------------
I don't think we will be able to support deploy providers as OSGi bundles
anymore and have them used automatically by the JVM through the usual APIs.
The reason is that what we do in the {{apache-karaf}} distribution it to deploy
hacked versions of the specs, however, there will be no apache licensed version
of those specs that works with java 9 in the short term.
What can be done is the following:
* add a {{[KARAF_HOME]/lib/modules}} directory which will contain Java 9
modules
* add those modules to the module path using {{--module-path}} option for
javac
* eventually export the packages from the system bundle
The obviously remove some dynamism because the providers can't be deployed as
OSGi bundles at runtime.
If the client code supports it, some providers can be deployed as OSGi bundles
instead, but the requirement will be for the client code to not use the usual
factories to create instances of the providers, but to instantiate them
directly.
