> Installation of the second subsystem fails with the message

> gogo: SubsystemException: org.osgi.service.resolver.ResolutionException: Uses constraint violation. Unable to resolve resource org.ops4j.pax.web.pax-web-jetty-bundle [124.0] because it exports package 'org.apache.xbean.finder.archive' and is also exposed to it from resource org.apache.xbean.finder [98.0] via the following dependency chain:
> org.ops4j.pax.web.pax-web-jetty-bundle [124.0]
> import: (osgi.wiring.package=org.apache.xbean.finder)
> export: osgi.wiring.package: org.apache.xbean.finder; uses:=org.apache.xbean.finder.archive
> export: osgi.wiring.package=org.apache.xbean.finder.archive
> org.apache.xbean.finder [98.0]
> {quote}
> Before failing a lot of similar messages are logged with the message "DEBUG: Candidate permutation failed due to a conflict between an export and import; will try another if possible."
> This is especially weird since pax-web-jetty-bundle does not expose the org.apache.xbean.finder.archive package (see attached Jar). Both pax-web-jetty-bundle and org.apache.xbean.finder are only present in the first subsystem.
> In our setup pax-web-jetty-bundle is a fragment-host for a fragment which is in the same (first) subsystem. Similar DEBUG statements are printed for other fragment-hosts in the first subsystem.
> The issue occurs since commit 4c0437de06f34321909a6132a7f2be163b2f6d5. In earlier versions, we had no issues for these subsystems
