[CDO] harmless runtime exception during osgi shutdown [message #1832842]

We always see this during the shutdown for an Eclipse RCP application which uses CDO.

It seems to be harmless, but I would like to get rid of it.
I created a small sample project which simulates this (see attachment).
A second attachment shows the stacktrace.

The exception only appears if the feature.xml includes the feature for RCP applications: org.eclipse.e4.rcp

Is this some misconfiguration on our side?

With the debugger I could find out that the Felix Gogo shell, during its Activator stop, interrupts the wrong thread, i.e., the Equinox stop thread itself instead of the Gogo Shell thread. You can quickly verify that your problem goes away by removing Gogo from your product launch.

Google then showed that it's a known problem in Felix: https://issues.apache.org/jira/browse/FELIX-6046

And it's fixed in gogo.shell-1.1.4: https://github.com/apache/felix/pull/181/commits/ff104db634f48d9009eb51f156400586272c3a29

Unfortunately Eclipse Orbit and, hence, the Platform only contains gogo.shell-1.1.0. I suggest that you submit a bug against the platform and ask for an upgrade of the gogo shell.

Cheers
