------------------------------------
Summary: 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
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
