[jira] [Updated] (LOG4J2-3102) Asynchronous Logger WAITS
indefinitely after end of main method
[ https://issues.apache.org/jira/browse/LOG4J2-3102?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Philip Hachey updated LOG4J2-3102:
----------------------------------
Description:
When running a Java 8 console application on Linux while a Log4j2 asynchronous logger is configured, the "Log4j2-AsyncAppenderEventDispatcher-1-AsynAppenders" thread remains in a "WAITING (parking)" state even after the end of the application's "main" method is reached. This prevents the JVM from exiting and the console application from terminating.
*This is a NEW issue as of 2.14.1. Log4j 2.14.0 does not have this problem.*
