> We had a broken component that failed to start (for a good reason): 
> {code:java}
> @Component(provides = Object.class)
> public class BrokenComponent {
>     static final Locale defaultLocale = Locale.forLanguageTag(System.getProperty("not.set"));
> }
> {code}
> The problem is not that it doesn't work BUT the error log  (see below) never reached our central logging (which is consuming the log messages from the LogService). 
> I this is caused by the fact that this is not an {{Exception}} but an {{Error}}, that makes it propagate all the way to the {{SerialExecutor}} which is initialized with a new {{Logger}} instance in {{ComponentImpl}} instead of getting the {{Logger}} instance that was used to create the {{ComponentImpl}}.
