Description

The following exception occurs when metatype service is missing:

java.lang.NullPointerException
        at org.apache.felix.webconsole.internal.configuration.ConfigAdminSupport.getConfigurationPropertyValueOrDefault(ConfigAdminSupport.java:703)

This is probably related to FELIX-4710

As result all configurations are missing and the plugin becomes completely unusable.
