EvaluatorFilter returns OnMatch when marker is null --------------------------------------------------- Key: LBCORE-118 URL: http://jira.qos.ch/browse/LBCORE-118 Project: logback-core Issue Type: Bug Components: Other Affects Versions: 0.9.17 Environment: Windows XP Reporter: Manuel Kueblboeck Assignee: Logback dev list Priority: Minor <appender name="Alert" class="ch.qos.logback.core.ConsoleAppender"> <filter class="ch.qos.logback.core.filter.EvaluatorFilter"> <evaluator name="isAlert"> <expression>marker.getName().equals("Alert")</expression> </evaluator> <OnMatch>ACCEPT</OnMatch> <OnMismatch>DENY</OnMismatch> </filter> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>ALERT: %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern> </layout> </appender> In the above example, when an event is logged without an attached marker, the filter returns OnMatch. I would expect that it returns OnMismatch. A work around for this issue is to change the expression to this: <expression>marker != null && marker.getName().equals("Alert")</expression> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
