Dirk Rudolph commented on SLING-10434:
--------------------------------------

I extended 
[RegionConfigurationTest#testLoadBundleFeatureMapAndConfig|https://github.com/apache/sling-org-apache-sling-feature-apiregions/pull/15/commits/46e30a435d44779b9da4736d75416dfcaa4ec4dc]
 to show the issue.

The 
[fix|https://github.com/apache/sling-org-apache-sling-feature-apiregions/pull/15]
 is simple, but I am not sure if is the expected behaviour. At least according 
to 
 
[sling-org-apache-sling-installer-factory-feature|https://github.com/Buuhuu/sling-org-apache-sling-installer-factory-feature/commit/a8f5a97fa8ea584539ad9675bd9fe4382a6207df]
 the case is possible.
