Ashish Chopra commented on SLING-8310:
--------------------------------------
The problem was that the class was made an OSGi {{@Component}} via SLING-7612
[0], but wasn't made {{public}}, thus SCR wasn't able to instantiate it -
making it {{public}} fixes the issue.

> Key: SLING-8310

> {{/system/console/mimetypes}} is broken in v2.2.0 of CoOmmons MIME - post [0]
> {{org.apache.sling.commons.mime.internal.MimeTypeWebConsolePlugin}} stays
> unsatisfied, so the "Sling MIME Types" printer entry doesn't appear in the
> system-console's Sling menu.
> However, in subsequent commit (specifically due to [1]), the printer entry
> does appear in the Menu (because the component is now satisfied), but the
> page fails to load with stack-trace at [2] since the component fails
> activation due to {{java.lang.InstantiationException: Constructor not found}}.
