Description

See https://github.com/apache/logging-log4j2/pull/75

trim levels after reading them from properties and before initializing any loggers.

If the level in a properties file contains a trailing space log4j2 won't initialize the logger correctly. In Effect the logger for whicht the level is defined will keep the inherited loglevel.
