Hi Apache devs,
I'm trying to use org.apache.felix.configurator version 1.0.10 in an OSGi
enRoute project. EnRoute uses 1.0.6 by default, but I'm trying to bump the
version to see if it addresses what might be a lifecycle bug (that's a
topic for a separate email).
Initially there were some problems resolving the bundle, so 1.0.10 has an
import that was not required in 1.0.6:
[ERROR] Resolution failed. Capabilities satisfying the following
requirements could not be found:
[<<INITIAL>>]
⇒ osgi.identity: (osgi.identity=org.example.app)
⇒ [org.example.app version=0.0.1.202005190718]
⇒ osgi.extender:
(&(osgi.extender=osgi.configurator)(version>=1.0.0)(!(version>=2.0.0)))
⇒ [org.apache.felix.configurator version=1.0.10]
⇒ osgi.wiring.package:
(&(osgi.wiring.package=javax.json)(&(version>=1.0.0)(!(version>=2.0.0))))
I tried adding org.apache.geronimo.specs:geronimo-json_1.0_spec (which is
listed as a provided scope dependency of configurator) to the resolver
input as follows:
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-json_1.0_spec</artifactId>
<version>1.0-alpha-1</version>
<scope>runtime</scope>
</dependency>
This successfully resolves, but the Configurator now throws a CNFE from its
activator:
! Failed to start bundle org.apache.felix.configurator-1.0.10, exception
activator error org.apache.johnzon.core.JsonProviderImpl not found from:

I am running on Java 11 (AdoptOpenJDK build 11.0.7+10). What combination of
bundles does Configurator actually require? Why does this bundle allow a
correct resolution of imports but then throw a CNFE at runtime? Note that
configurator 1.0.6 embeds geronimo-json_1.0_spec-1.0-alpha-1.jar,
johnzon-core-1.0.0.jar and org.apache.felix.converter-1.0.0.jar using
Bundle-ClassPath, but this is no longer the case in 1.0.10. That seems like
an error.
Regards,
Neil
