Throwable t is passed to underlying SLF4J Logger implementation even if it is null, which causes the following method signature to apply, which is wrong: {code:java} Logger.trace(Marker marker, String format, Object arg1, Object arg2){code} There should be a check in this method, if Throwable t argument is null, then call: {code:java} Logger.trace(Marker marker, String format, Object arg){code} -- This message was sent by Atlassian JIRA (v7.3.1#73012)
