-------------------------------------
Summary: Log4jLogger only accepts Log4jMarker, not SLF4J's Marker
Key: LOG4J2-793
URL: https://issues.apache.org/jira/browse/LOG4J2-793
Project: Log4j 2
Issue Type: Bug
Affects Versions: 2.0.1
Reporter: Manfred Dohmen
Priority: Minor
We're using Log4j 2 via SLF4J. A Logger's log methods have signatures like this:
public abstract void warn(org.slf4j.Marker marker, java.lang.String msg)
If you use an object that is an Marker but not a Log4jMarker this fails at
org.apache.logging.slf4j.Log4jLogger.getMarker(Log4jLogger.java:378) due to
"cannot be cast to org.apache.logging.slf4j.Log4jMarker".
Use case: we have a defined set of Markers. There's an enum for this,
implementing SLF4J's marker interface. Obviously with Log4j we cannot use this
enum.
I think an org.apache.logging.slf4j.Log4jLogger cannot expect an
org.apache.logging.slf4j.Log4jMarker.
