             Summary: ConfigInstaller should only handle events for 
configurations it manages
                 Key: FELIX-5832
                 URL: https://issues.apache.org/jira/browse/FELIX-5832
             Project: Felix
          Issue Type: Bug
          Components: File Install
    Affects Versions: fileinstall-3.6.2, fileinstall-3.6.0
            Reporter: Chris Drake
         Attachments: ConfigInstaller.diff

Recent changes introduced by FELIX-5609 have caused ConfigInstaller to 
incorrectly write configuration objets which it does not manage to disk.

For example, given:

{{felix.fileinstall.filter=.*\\.cfg|.*\\.json}}

and a CustomConfigInstaller implementing the ArtifactInstaller and 
ConfigurationListener interfaces for .json configuration files, the expectation 
is that .cfg files will be installed and written back to disk by Felix's 
ConfigInstaller.  Any .json configuration files will be installed and written 
to disk by the CustomConfigInstaller. Unfortunately since FileInstall 3.6.0, 
.json config files written to disk by the CustomConfigInstaller are overwritten 
by Felix's own ConfigInstaller.

The regression is caused by a change to the ConfigInstaller, whereby 
ConfigurationEvents for _*all configuration objects*_ are handled as apposed to 
previous behaviour where only those configuration objects managed by the Felix 
ConfigInstaller (aka .cfg and .config) are managed.
