Hot deploy is when you load a new version of a war for example while the server is still running. This triggers a chain of init actions on the server side.
I see from the logs the doGet method in the servlet caused a init of log4j configuration. try looking in that direction. I think this should not happen. The exception logged indicates a class file was changed in the middle of using it (or something like that). these things sometime happen when using hot deploy.
