This is a real mess. There seems to be an RMI exception, except that
Tomcat isn't an RMI server. It's seems to think you are sending a "chunked" request, but the chunks are mal-formed. And finally, it looks like you are using the coyote jk Apache connector and it doesn't like what's coming in from there.
I think I'd start by looking and the Apache and Tomcat mod_jk configurations.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
