Subject [jira] [Commented] (KARAF-3518) JDK9: endorsed directories not working any longer
Date Thu, 24 Nov 2016 14:58:58 GMT

    [ https://issues.apache.org/jira/browse/KARAF-3518?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15693484#comment-15693484

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.
