This is a vote to release Log4j 2.11.1, the next version of the Log4j 2 project.
Please download, test, and cast your votes on the log4j developers list. [] +1, release the artifacts [] -1, don't release because... The vote will remain open for 72 hours (or more if required). All votes are welcome and we encourage everyone to test the release, but only Logging PMC votes are “officially” counted. As always, at least 3 +1 votes and more positive than negative votes are required. Changes in this release include: Fixed Bugs • LOG4J2-2389: ThrowableProxy was saving and retrieving cache entries using different keys. Thanks to Liu Wen. • LOG4J2-2316: If root LoggerConfig does not have a Level return ERROR. • LOG4J2-2390: Fix broken links in log4j web documentation. Thanks to anton-balaniuc. • LOG4J2-2343: The OSGi Activator specified an incorrect version. Thanks to Raymond Augé. • LOG4J2-2305: Make java.util.ServiceLoader properly work in OSGi by using the Service Loader Mediator Specification. Thanks to Björn Kautler. • LOG4J2-2305: Split the SLF4J binding into 2 implementations - one for SLF4J 1.7.x and one for SLF4J 1.8+. • LOG4J2-2268: Improve plugin error message when elements are missing. Thanks to Tilman Hausherr. • LOG4J2-2283: ParserConfigurationException when using Log4j with oracle.xml.jaxp.JXDocumentBuilderFactory. Thanks to Vishnu Priya Matha. • LOG4J2-2300: PoolingDriverConnectionSource does not take into account properties, user name, and password. • LOG4J2-2307: MutableLogEvent and RingBufferLogEvent message mementos retain the original format string. • LOG4J2-2032: Curly braces in parameters are not treated as placeholders. Thanks to Kostiantyn Shchepanovskyi. • LOG4J2-2317: MutableLogEvent.getNonNullImmutableMessage and Log4jLogEvent.makeMessageImmutable retain format and parameters. • LOG4J2-2318: Messages are no longer mutated when the asynchronous queue is full. A warning is logged to the status logger instead. • LOG4J2-2320: Fix NPE in AbstractLogger when another exception is thrown, masking the root cause. • LOG4J2-2321: AsyncLogger uses the correct level when unspecified. This provides parity between AsyncLogger and Logger. • LOG4J2-2322: Custom ContextSelector implementations which select an AsyncLoggerContext disable LoggerConfig.includeLocation by default for parity with AsyncLoggerContextSelector. • LOG4J2-2269: MutableLogEvent references to other objects are cleared after each use. Fix a memory leak causing references to parameters to be held after synchronous logging with thread locals enabled. • LOG4J2-2301: Mixed async loggers no longer forget parameter values, providing some appenders with an array of nulls. • LOG4J2-2331: RollingFileManager debug logging avoids string concatenation and errant braces in favor of parameterized logging. Thanks to Mike Baranski. • LOG4J2-2333: Handle errors thrown in default disruptor ExceptionHandler implementations to avoid killing background threads. • LOG4J2-2334: Add API org.apache.logging.log4j.core.appender.AsyncAppender.getQueueSize(). • LOG4J2-2336: Remove duplicate hyphen from the AsyncLoggerConfig background thread name. • LOG4J2-2347: Update Apache Commons Compress from 1.16.1 to 1.17. • LOG4J2-2352: RingBufferLogEvent memento messages provide the expected format string, and no longer attempt to substitute parameters into curly braces in parameter toString values. Both RingBufferLogEvent and MutableLogEvent memento implementations memoize results to avoid rebuilding formatted string values. • LOG4J2-2355: PropertiesUtil ignores non-string system properties. Fixes a NoClassDefFoundError initializing StatusLogger caused by an NPE while initializing the static PropertiesUtil field. Thanks to Henrik Brautaset Aronsen. • LOG4J2-2362: Fixed a memory leak in which ReusableObjectMessage would hold a reference to the most recently logged object. • LOG4J2-2312: Jackson layouts used with AsyncLoggerContextSelector output the expected format rather than only a JSON string of the message text. • LOG4J2-2364: Fixed a memory leak in which ReusableParameterizedMessage would hold a reference to the most recently logged throwable and provided varargs array. • LOG4J2-2368: Nested logging doesn't clobber AbstractStringLayout cached StringBuidlers • LOG4J2-2373: StringBuilders.escapeJson implementation runs in linear time. Escaping large JSON strings in EncodingPatternConverter and MapMessage will perform significantly better. Thanks to Kevin Meurer. • LOG4J2-2376: StringBuilders.escapeXml implementation runs in linear time. Escaping large XML strings in EncodingPatternConverter and MapMessage will perform significantly better. Thanks to Kevin Meurer. • LOG4J2-2377: NullPointerException in org.apache.logging.log4j.util.LoaderUtil.getClassLoaders() when using Bootstrap class loader. Thanks to Mirko Rzehak, Gary Gregory. • LOG4J2-2382: Update Mongodb 3 driver from 3.6.3 to 3.8.0. • LOG4J2-2388: Thread indefinitely blocked when logging a message in an interrupted thread. Thanks to Failled. Changes • LOG4J2-1721: Allow composite configuration for context parameter. Thanks to Phokham Nonava. • LOG4J2-2302: Status logger should show the Log4j name and version when initializing itself. • LOG4J2-2304: Log4j2 2.8.2 JMX unregister NullPointerException. Thanks to wumengsheng. • LOG4J2-2311: Update Jackson from 2.9.4 to 2.9.5. • LOG4J2-2313: Update LMAX Disruptor from 3.3.7 to 3.4.2. • LOG4J2-548: Log4j 2.0 ERROR "Could not search jar" with JBoss EAP 6.2. Thanks to Shehata, Paresh Varke, Eric Victorson, Martin Laforet. • LOG4J2-2328: Update JAnsi from 1.17 to 1.17.1. • LOG4J2-2351: Added AbstractLogEvent.getMutableInstant to allow the MutableInstant instance to be modified by classes extending AbstractLogEvent. • LOG4J2-2357: Update Jackson from 2.9.5 to 2.9.6. • LOG4J2-2358: Update Kafka client from 1.0.0 to 1.1.0. • LOG4J2-2384: Update Kafka client from 1.1.0 to 1.1.1. • LOG4J2-2385: Update Groovy from 2.4.13 to 2.5.1. • LOG4J2-2386: Update optional Apache Commons DBCP from 2.2.0 to 2.4.0.
