[jboss-jira] [JBoss JIRA] (WFLY-3111) Accessing attribute message from class LoggingEvent always returns class String

Accessing attribute message from class LoggingEvent always returns class String ------------------------------------------------------------------------------- Key: WFLY-3111 URL: https://issues.jboss.org/browse/WFLY-3111 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Logging Affects Versions: 8.0.0.Final Environment: Windows 7, JDK 1.7.0_51 Reporter: Jörg Brück Assignee: James Perkins Priority: Minor After Changing from JBoss 5.1.0 to Wildfly the behaviour of my own written Log4j appenders have changed while accessing LoggingEvent in the function "append" of class ApppenderSkeleton. The reason of this behaviour is the implementation of org.apache.log4j.spi.LoggingEvent public LoggingEvent(String fqnOfCategoryClass, Category logger, long timeStamp, Priority level, Object message, Throwable throwable) { this.fqnOfCategoryClass = fqnOfCategoryClass; this.logger = logger; this.level = level; logRecord = new ExtLogRecord(JBossLevelMapping.getLevelFor(level), message == null ? null : message.toString(), ExtLogRecord.FormatStyle.NO_FORMAT, fqnOfCategoryClass); The Object message is converted to string and saved in Class ExtLogRecord. Here the implementation of getMessage: public Object getMessage() { return logRecord.getMessage(); } Here the implementation of getMessage of ExtLogRecord public String getMessage() { return message; } Because of this String is always returned. If I understand this code right you can transfer every object to log4j, but you can not access this objects in an appender because of the LoggingEvent constructor where method toString is called. What is the reason of this change in contrast to jboss 5.1.0? Of course I can reconstruct my objects from the string if I overwrite the toString method.
