Description

If I define a custom Plugin for Lookups it is recognized by log4j2 but the Interpolator class does not find the Plugin.

Interpolator.lookup(...) tries to find the key inside its lookups Map but the key in the map is .toLowerCase() and the extracted prefix not. So there is no match.

Defining my Plugin name with lower chars is working.
