Sometimes JerseyServlet fails to start because InjectionManagerFactory can't be found

Sometimes JerseyServlet fails to start because InjectionManagerFactory can't be found.

Example from karaf.log:

15:34:33.571 WARN  [features-3-thread-1] unavailable
java.lang.IllegalStateException: InjectionManagerFactory not found.

The problem is spurious: my most common workaround is to clear the karaf data directory and keep reinstalling until the problem goes away.

I googled and found this explanation: the jersey-inject-hk2 maven dependency is missing

The jersey-inject-hk2 OSGi bundle is available at run time and it is loaded by the jersey-karaf-feature.

My theory is that it has something to do with load order. I.e. that if the jersey-inject-hk2 bundle is loaded before any bundles containing JerseyServlet, then the problem never occurs.

I've tested this by installing the jersey-karaf-feature before installing features that pulls in JerseyServlet and this makes the issue go away. But since the issue is spurious I can't be sure that I have a fix/workaround.

I've noticed that the jersey-inject-hk2 OSGi bundle offers up a package that isn't used anywhere:

karaf@root()> bundle:list | grep hk2
140 x Active x  80 x 2.30.1                x jersey-inject-hk2
karaf@root()> bundle:capabilities 140
org.glassfish.jersey.inject.jersey-hk2 [140] provides:
------------------------------------------------------
osgi.wiring.bundle; org.glassfish.jersey.inject.jersey-hk2 2.30.1 [UNUSED]
osgi.wiring.host; org.glassfish.jersey.inject.jersey-hk2 2.30.1 [UNUSED]
osgi.identity; org.glassfish.jersey.inject.jersey-hk2 2.30.1 [UNUSED]
osgi.wiring.package; org.glassfish.jersey.inject.hk2 2.30.1 [UNUSED]
karaf@root()>

Theory: if I can make JerseyServlet import the org.glassfish.jersey.inject.hk2 this should force the jersey-inject-hk2 bundle to always be loaded and made active before any bundle using JerseyServlet.
