[jira] [Commented] (SOLR-9425) TestSolrConfigHandlerConcurrent failure: NullPointerException

JIRA jira@apache.org

    [ https://issues.apache.org/jira/browse/SOLR-9425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16659217#comment-16659217 ]

Christine Poerschke commented on SOLR-9425:
-------------------------------------------

I think this is a problem with the test where two threads could do {{collectErrors.add(...);}} at the same time. Attached proposed patch, which somehow seems too easy though?
