[jira] [Commented] (ARIES-1443) After a restart the capabilities of a subsystem have changed (seem correct) before the restart they seem wrong

Wouter Bancken commented on ARIES-1443:
---------------------------------------

The commit done for this issue seems to have broken the deployment of our application. If I use a version before commit 74c0437de06f34321909a6132a7f2be163b2f6d5, our deployment works. 
Before commit 74c0437de06f34321909a6132a7f2be163b2f6d5, the getCapabilities method only returned the identity capability for our subsystems. Now it returns the union of all capabilities of the subsystems content (as intended by the commit). This exposure of the capabilities seems to interfere with the bundle wiring.

Our setup contains two feature subsystems. The errors arise during the installation of the second subsystem and are all similar to the following:

DEBUG: Candidate permutation failed due to a conflict between an export and import; will try another if possible. (org.osgi.service.resolver.ResolutionException: Uses constraint violation. Unable to resolve resource org.ops4j.pax.web.pax-web-jetty-bundle [195.0] 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 [195.0]
    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])

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.

> A feature subsystem should export all capabilities of its constituents and it does not do that after a fresh install. After a restart of the subsystem core bundle it will export all the capabilities. 
> These seems to be a difference in parsing the capabilities of a persisted subsystem and a new subsystem.
