Karaf 4.4.3 Fails binding services

[Ephemeris Lappis <ep...@gmail.com>]

Hello.

I don't understand why with 5 bundles, all packaged and installed as
features, one of them has been failing with an "lying" error about
missing services. The 5 bundles use the same services, and 4 have been
started with no issue, and the last one has started normally after a
restart of Karaf.

All the bundles are built with a same pattern with the resulting manifest :

Manifest-Version: 1.0
Bnd-LastModified: 1675929825182
Build-Jdk-Spec: 11
Bundle-Blueprint: OSGI-INF/blueprint/context_comacc016.xml

Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=11))"
Tool: Bnd-6.3.1.202206071316

The two services below are present (ls) and the other 4 bundles resolved them :
- info.xxxxxx.yyyyy.com.caterpillar.buddy.ExchangeBuddy
- com.caterpillar.buddy.CaterpillarMDCUnitOfWorkFactory

The error : waiting for dependencies
[(objectClass=info.xxxxxx.yyyyy.com.caterpillar.buddy.ExchangeBuddy),
(objectClass=info.xxxxxx.yyyyy.com.caterpillar.buddy.CaterpillarMDCUnitOfWorkFactory)]

What can explain the failure when I install the 5th feature, and not
the other, and why all is OK after a restart ? Note that restarting
the failing bundle didn't work.

Thanks for your help.

Regards.
