[jira] [Commented] (SOLR-15198) Slf4j logs threadName incorrectly
in some cases
[ https://issues.apache.org/jira/browse/SOLR-15198?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17298544#comment-17298544 ]
David Smiley commented on SOLR-15198:
-------------------------------------
I think these thread names with MDC is deliberate. See org.apache.solr.common.util.ExecutorUtil.MDCAwareThreadPoolExecutor#execute

> Key: SOLR-15198
> URL: https://issues.apache.org/jira/browse/SOLR-15198
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: logging
> Affects Versions: 8.6
> Reporter: Megan Carey
> Priority: Minor

> I'm running Solr 8.6, and I'm seeing some logs report threadName with the entire log message and MDC. I haven't dug in too much, but CoreContainer logs seem to be the biggest culprit. Not sure if it's an issue of thread naming (including delimiter in name?), SolrLogFormat parsing, or something else altogether.
