----------------------------------------
Raised FELIX-4346 for improving the logic, though I'm not even convinced yet
it's a good idea.
> FileInstall throws Interrupted exception when refreshed

> Key: FELIX-3712
> URL: https://issues.apache.org/jira/browse/FELIX-3712
> Project: Felix
> Issue Type: Bug
> Components: File Install
> Affects Versions: fileinstall-3.2.4, fileinstall-3.2.6
> Reporter: Per-Erik Svensson
> Assignee: Guillaume Nodet
> Fix For: fileinstall-3.2.8

> FileInstall will throw exception when refreshing. It is possible there are
> easier ways to reproduce this but here is one way:
> 1) Uninstall gogo command (if available) from the osgi container.
> 2) Install fileinstall
> 3) Put gogo command in the directory watched by fileinstall
> Result: Fileinstall throws
> In main loop, we have serious trouble: java.lang.RuntimeException:
> java.lang.InterruptedException
> java.lang.RuntimeException: java.lang.InterruptedException

> Possible reason: Due to FELIX-3414, the refresh() method in DirectoryWatcher
> was changed from calling
> packageAdmin#refreshPackages() directly, to using the FileInstall#refresh()
> helper method. The later wraps interrupted excpetions in a runtime exception
> which is never caught in the directory watcher's main loop. Thus, the
> directory watcher will re-throw the exception, which it previously did not
> (since the interrupted excpetion would get caught).
