Rufus created SLF4J-432: --------------------------- Summary: log4j-over-slf4j calls wrong methods when marker parameter is null Key: SLF4J-432 URL: https://jira.qos.ch/browse/SLF4J-432 Project: SLF4J Issue Type: Bug Components: log4j-over-slf4j Reporter: Rufus Assignee: SLF4J developers list Priority: Minor The org.slf4j.Logger interface has with-Marker and without-Marker versions of each logging method, e.g. public void trace(Marker marker, String format, Object arg); vs public void trace(String format, Object arg);   However, the differentiatedLog method in log4j-over-slf4j ignores this and always calls the method *with* the Marker argument, even when there is no Marker. Logger implementations are then forced to defensively check for null Markers because of this error. log4j-over-slf4j should instead call the correct (without-Marker) method when there is no Marker.   Patch: https://github.com/qos-ch/slf4j/pull/190/ -- This message was sent by Atlassian JIRA (v7.3.1#73012)
