commit f01ef78305ceb8057ac594038084cc2fef684cbd
Author: Mark Thomas <ma...@apache.org>
AuthorDate: Fri Nov 22 18:42:27 2024 +0000

    Fix BZ 69471
    
    Log instances of CloseNowException caught by
    ApplicationDispatcher.invoke() at debug level rather than error level as
    they are very likely to have been caused by a client disconnection or
    similar I/O issue.
