      Summary

      The class "web.csskit.antlr.CSSLexer" spams a WARN message in the Confluence logs when a mail notification is sent.

      Steps to Reproduce

      1. Install a fresh Confluence instance
      2. Create two users with valid email addresses
      3. Configure a Mail Server
      4. Log in as User1, create a page and mention User2 on it, in order to trigger a mail notification

      Expected Results

      An email is sent successfully without any warnings in the logs.

      Actual Results

      The email is sent successfully, but the following messages are shown in the atlassian-confluence.log:

      2018-09-26 15:55:26,993 WARN [NotificationSender:thread-2] [web.csskit.antlr.CSSLexer] mIMPORT Base URL is unknown

      Notes

      • Other scenarios that trigger a mail notification would be enough to reproduce the issue.
      • The messages can appear at regular intervals depending on the frequency of the Scheduled Job that flushes the mail queue.

      Workaround

      Although there is no workaround, the WARN messages are harmless and can be safely ignored.

      If the warnings needs to be suppressed, the following package can be configured to have a logging level of ERROR.

      cz.vutbr.web.csskit.antlr

            How is it not possible to suppress this in the logging settings?

            Thanks for finding out...

            I experienced the same and had no clue, where these message originate from. My Log files are cluttered with those messages.
