David Bosschaert updated DOSGI-157:
-----------------------------------
Description:
When configuring Discovery with the Single-Bundle distribution a
NoClassDefFoundError occurs and discovery does not start up.
To reproduce, place a org.apache.cxf.dosgi.discovery.zookeeper.cfg file in the
{{load}} directory with the following content:
{code}zookeeper.host = 127.0.0.1{code}
When the CXF-DOSGi bundle is started the following error appears:
{code} *ERROR* [org.osgi.service.cm.ManagedService, id=25, bundle=5]:
Unexpected problem updating Configuration
PID=org.apache.cxf.dosgi.discovery.zookeeper, factoryPID=null,
bundleLocation=file:/Users/david/checkouts/cxf_dosgi_240113/distribution/single-bundle/target/cxf-dosgi-ri-singlebundle-distribution-1.5-SNAPSHOT.jar

While CXF-DOSGi has migrated to use SLF4J, the embedded zookeeper code still
uses Log4J. Log4J is currently not provided in the single bundle distro nor
marked as imported. The classloader manages to get access to it because of the
Dynamic-ImportPackage=* which is present in the CXF-DOSGi Single-Bundle distro
(yuck).
As the Single-Bundle distro is really about convenience, it should also provide
the Log4J classes so that the discovery code will work without providing any
additional bundles.
