Ralph Goers commented on LOG4J2-3440: ------------------------------------- I'm not really sure how your test succeeds. When you reference LogManager it has a static block that will initialize Log4j. By default, it will configure the DefaultConfiguration, which has a root LoggerConfig at ERROR and a Console Appender. See [setDefault() in AbstractConfiguration|https://github.com/apache/logging-log4j2/blob/release-2.x/log4j-core/src/main/java/org/apache/logging/log4j/core/config/AbstractConfiguration.java#L723]. > Log4j 1.2 bridge getAllAppenders() returns null enumeration > ----------------------------------------------------------- > > Key: LOG4J2-3440 > URL: https://issues.apache.org/jira/browse/LOG4J2-3440 > Project: Log4j 2 > Issue Type: Bug > Components: Log4j 1.2 bridge > Affects Versions: 2.17.2 > Reporter: Pablo Rogina > Assignee: Piotr Karwasz > Priority: Major > Fix For: 2.17.3 > > > Old application using Log4j 1.2.x relies on Logger.getAllAppenders() to > decide if Log4j it's already configured (returned Enumeration has at least 1 > appender) or not (empty returned Enumeration). > Some recent code audits mandate to remove log4j v1 component(s) and to > upgrade to latest 2.17.2 release, so we're using Log4j 1.2 Bridge to comply > and not to change application code. > However, we're facing the issue describe here [1] for > Logger.getRootLogger().getAllAppenders() although with latest Log4j release > 2.17.2 the issue seems to be that data structure aai is never updated with > the proper configured appenders, given that now most of the work happens in > the Log4j v2 Core implementation, thus using LoggerContext > [1] [java - Log4j getAllAppenders() returns null enumeration - Stack > Overflow|https://stackoverflow.com/questions/32864929/log4j-getallappenders-returns-null-enumeration] > > -- This message was sent by Atlassian Jira (v8.20.1#820001)
