[FELIX-6152] NPE when logging with Felix Log

Description

Calling the logger like this:

log.info("Test", new Object[0]);

causes a NPE:java.lang.NullPointerException
    at org.apache.felix.log.LoggerImpl.format(LoggerImpl.java:335)
    at org.apache.felix.log.LoggerImpl.info(LoggerImpl.java:164)

While you wouldn't explicitly write code like this, wrappers such as org.eclipse.jetty.util.log.Slf4jLog may introduce a "mapping" of info(msg) to info(msg, Object[0])
