[jira] [Commented] (LOG4J2-1990) ConcurrentModificationException logging a parameter of type Map
[ https://issues.apache.org/jira/browse/LOG4J2-1990?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17686726#comment-17686726 ]
Gus Heck commented on LOG4J2-1990:
----------------------------------
Hmm this makes debugging custom appenders that rely on ThreadContext difficult. Stack trace only tells me which class was involved, no way to catch the exception on it's way up and add info about which of a dozen possible configured instances is putting a null in the context when that should theoretically be impossible. The ability to bubble things up via configuration (preferably something I can stick in the log4j2.xml either globally or for specific appenders) would certainly help.
