Hi, I normally run tomcat8 (build 8.0.33) in a command window - easier to monitor the log that way. When closing that windows, I'm getting a number of errors - there's no indications that these errors affect the database negatively, but (as always) I don't like getting errors or warnings that ideally should not be there.
Anybody able to cast some light on the root cause of these errors?
