Description

With fixing FELIX- 2009 the field webManagerRoot is only assigned if the OsgiManager is bound to the Http Service. If the OsgiManager starts and is configured before the Http Service is registered, the field remains unset and registration of the Http Service may cause the following dump:

The only resolution here is to restart the WebConsole bundle or reconfigure the Web Console for the registration to take place again.
