Log4j Logger.getParent() inconsistent ------------------------------------- Key: LOGMGR-95 URL: https://issues.jboss.org/browse/LOGMGR-95 Project: JBoss Log Manager Issue Type: Bug Security Level: Public(Everyone can see) Reporter: James Livingston Assignee: David Lloyd Log4j Loggers have a getParent() method, whose return value is set up by JBossLogManagerFacade.updateParents(). The method locates the closest parent node which has an existing Log4J logger created *at the time*. This results in the parent being different depending on the order Log4j loggers are used in. Consider: Logger.getLogger("a"); Logger.getLogger("a.b.c"); Logger.getLogger("a.b"); When the second line causes updateParents() to be called, LoggerNode.getOrCreate() has already created the intermediate "a.b" node. That does not yet have a Log4j Logger created, so the Logger for "a" is returned. Original log4j would have returned "a.b" due to it using the parent structure in the implementation.
