During shutdown of Tomcat I'm getting the same bug. It looks like it has some
problems with JMS, but even in that case, it should not fail. I looked into the
code and it seems to fail on

  public void debug(Object message) {
    logger.log(null, FQCN, LocationAwareLogger.DEBUG_INT,
String.valueOf(message), null);
  }

which is quite strange, it can only happen if logger is null. Now: transient
loggers can become null, so it might be related to this?!

  private transient LocationAwareLogger logger;
