Description

I'm running a jackrabbit locally and have my java client connected to it via webdav (http://localhost:8080/server).
When i briefly shutdown jackrabbit and restart it again (to simulate a connection failure) my logs are completely flooded (>10 messages per second). Besides, the session does not reconnect / heal itself automatically.
