The file handler stops any logging output after changing "encoding" attribute in JBoss EAP 7

Issue

When setting encoding attribute on the file handler (file-handler, periodic-rotating-file-handler, size-rotating-file-handler, and periodic-size-rotating-file-handler) in CLI on JBoss EAP 7, LogManager throws the following error message in the console log and stops any logging output to the file handler:
