[jira] [Updated] (FELIX-4209) SCR seems to loads ConfigAdmin class
through DS bundle
[ https://issues.apache.org/jira/browse/FELIX-4209?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Christoph Läubrich updated FELIX-4209:
--------------------------------------
Description:
I have the following scenario:
- Equinox Service bundle providing org.osgi.service.cm version="1.3.0"
- DS Component using org.osgi.service.cm in version="1.3.0"
- Felix ConfiguarationAdmin providing version="1.5.0"
- Felix SCR
The component fails to initilize because of a ClassCastException that the Apache Felix CM impl can't be cast to org.osgi.service.cm.ConfigurationAdmin
MESSAGE [-component name-] Cannot register Component
!STACK 0

It seems as if the SCR Bundle is fetching either the service or the Class through the DS bundle and thus is getting a wrong reference.
Changing the DS providing bundle to use cm in version 1.5 fixes the issue, but of course makes it impossible for it to use an older package version.
