["Matt Sicker (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LOG4J2-1936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16046654#comment-16046654 ] 

Matt Sicker commented on LOG4J2-1936:
-------------------------------------

Do you get a similar error when using the normal context selector? The stack trace sounds like it wouldn't work, async or not.
