JBoss Logging throws NullPointerException when used with Log4j 2.0 final. -------------------------------------------------------------------------- Key: JBLOGGING-108 URL: https://issues.jboss.org/browse/JBLOGGING-108 Project: JBoss Logging Issue Type: Feature Request Security Level: Public(Everyone can see) Components: jboss-logging-log4j Affects Versions: 3.2.0.Beta1 Environment: <log4j.version>2.0</log4j.version> <jboss.logging.version>3.2.0.Beta1</jboss.logging.version> <hibernate.version>4.3.5.Final</hibernate.version> Reporter: Nayden Gochev Assignee: James Perkins Priority: Blocker When you enable logging of org.hibernate.SQL the log is not send to the log4j loggers/appenders. The reason for that is a null pointer exception in: Class: Log4j2Logger Method: protected void doLog(final Level level, final String loggerClassName, final Object message, final Object[] parameters, final Throwable thrown) { Line: 50 {code:title=Log4j2Logger.java|borderStyle=solid} @Override protected void doLog(final Level level, final String loggerClassName, final Object message, final Object[] parameters, final Throwable thrown) { final org.apache.logging.log4j.Level translatedLevel = Log4j2Logger.translate(level); if (this.logger.isEnabled(translatedLevel)) { try { this.logger.log(null, loggerClassName, translatedLevel, parameters == null || parameters.length == 0 ? this.messageFactory.newMessage(message) : this.messageFactory.newMessage(String.valueOf(message), parameters), thrown); } catch (Throwable ignored) { } } } {code} This this.logger.log call is the one causing NPE which is ignored .. because of the surrounding catch. If you change the call to something like : {code:title=Example (params are not passed but you can pas them as well )|borderStyle=solid} this.logger.log(translatedLevel,this.messageFactory.newMessage(String.valueOf(message), thrown) {code} As an example you will see its working.
