----------------------------------------------------------------

FYI: I also saw this error (and other similar ones) in the context of SLING-10143

If I recall correctly, that error during shutdown was somehow related to (or aggravated by) upgrading to org.osgi:org.osgi.service.log:1.5.0.   I didn't look into the details or reason, I just switched back to the 1.4.0 version for my project.  Maybe that error has always been happening, but it just wasn't logged before due to something that was changed in the 1.5.0 version?  Or perhaps the timing is just different with a different set of bundles. Updating to org.osgi:org.osgi.service.log:1.5.0 (or downgrading to org.osgi:org.osgi.service.log:1.4.0) may help reproduce what is different for anyone attempting to debug the problem.

> On stopping the Sling Starter with Ctrl+C we can occasionally see the following stacktrace:
> {code:java}

> This doesn't happen every time, but I've seen up to seven of these at a time (the number of stacktraces changes), see the attached file. This might be similar to SLING-10204 , although in the debugger I can see the ServiceUserMapped being mentioned, not ResourceResolverFactory.
