Summary: NPE in Log4J2Logger Key: IGNITE-6362 URL: https://issues.apache.org/jira/browse/IGNITE-6362 Project: Ignite Issue Type: Bug Components: general Affects Versions: 2.1 Reporter: Valentin Kulichenko Fix For: 2.3 When I start a node with {{Log4J2Logger}} configured and verbose mode ({{-DIGNITE_QUIET=false}}, it fails with NPE: {noformat} Caused by: java.lang.NullPointerException at org.apache.logging.log4j.core.config.LoggerConfig.<init>(LoggerConfig.java:145) at org.apache.logging.log4j.core.config.LoggerConfig.createLogger(LoggerConfig.java:523) at org.apache.ignite.logger.log4j2.Log4J2Logger.createConsoleLogger(Log4J2Logger.java:380) at org.apache.ignite.logger.log4j2.Log4J2Logger.addConsoleAppenderIfNeeded(Log4J2Logger.java:338) at org.apache.ignite.logger.log4j2.Log4J2Logger.<init>(Log4J2Logger.java:145) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:142) ... 34 more {noformat} This is caused by the fact that {{Log4J2Logger#createConsoleLogger}} method invokes {{LoggerConfig.createLogger}} providing {{null}} as {{Configuration}} object, which unconditionally causes NPE. Need to provide some default configuration instead. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
