Reduce verbosity of log levels

[guusdk]

Some unexpected situations are logged very verbosely. The conversion of a Session into an entity, for example, will log an error like this:

2024-11-15 10:36:36.910 ERROR [Jetty-QTP-AdminConsole-19336]: org.jivesoftware.openfire.plugin.rest.controller.SessionController - UnknownHostException
java.net.UnknownHostException: null
        at org.jivesoftware.openfire.nio.NIOConnection.getHostAddress(NIOConnection.java:159) ~[xmppserver-4.7.5.jar:4.7.5]
        at org.jivesoftware.openfire.session.LocalSession.getHostAddress(LocalSession.java:518) ~[xmppserver-4.7.5.jar:4.7.5]
        at org.jivesoftware.openfire.plugin.rest.controller.SessionController.convertToSessionEntities(SessionController.java:167) ~[?:?]
        at org.jivesoftware.openfire.plugin.rest.controller.SessionController.getAllSessions(SessionController.java:82) ~[?:?]
        at org.jivesoftware.openfire.plugin.rest.service.SessionService.getAllSessions(SessionService.java:53) ~[?:?]

Although (somewhat) unexpected, this is hardly an error. At the very least, it's not an error in the REST API, and it's not something that a consumer of the REST API can have an influence over.

Logging events like this needlessly pollutes log files. The log level should be reduced.
