Hi,
Till Karaf 4.1.x the endorsed libs delivered with karaf contain some servicemix
wrapped bundles for standard javax APIs. An example for this is the Stax API
(javax.xml.stream). These wrapped API bundles replace the implementation lookup
mechanism provided by the JDK with one also working in an OSGi environment.
With Karaf 4.2.0 these endorsed libraries were removed (because Java 9 does not
support endorsed libraries anymore). What is the idea how it might still be
possible to run Karaf 4.2.x with the woodstox Stax implementation?
If you just install the woodstox-bundles as with karaf 4.1.x, you will get the
following exception:
java.util.ServiceConfigurationError: javax.xml.stream.XMLInputFactory: Provider
com.ctc.wstx.stax.WstxInputFactory not found

Is there any idea how this might work? I am aware that as long as I am using
Java 8 I might just re-introduce the stax-api bundle to lib/endorsed, but what
are the ideas for this on Java 9?
Best regards
Stephan
