Hi,
When starting our custom Karaf distribution, we regularly see the error
below. I'm not sure I understand it OK, but it looks like the Felix
ConfigurationManager tries to log something, but an exception is thrown,
stopping the update-Thread. Maybe the eventAdmin bundle is restarted
somehow during boot, which makes it unavailable for a short period, but I
feel that a logLine should never have this kind of impact. At the bottom
you can find the configuration of our karaf-maven-plugin.
Can I prevent the eventAdmin bundle from being restarted, or should the
exception be handled differently somewhere ?
