"EXCEPTION" is the message logged
Browser-side some css/js/jpg are not downloaded with the following error 
message: Error 500 d != java.lang.String

It is a known issue?
It is possible that the bug is introduced by the following added code? (class 
org.eclipse.jetty.servlet.DefaultServlet)

if (LOG.isDebugEnabled()) {
 LOG.debug(String.format("uri=%s, resource=%s, content=%s", new Object[] { request.getRequestURI(), resource, content }), new Object[0]);
}

Thanks e Regards,

That debug call certainly looks suspect.

Sorry, I specific better the steps for reproduce the problem

What steps will reproduce the problem?
1. Install the version 1.6.2 of GitBlit Go
2. Add log4j file with DEBUG level configured (log4j.properties to use 
attached) under "data" folder
3. Add "-Dlog4j.configuration=file:C:\GitBlit\data\log4j.properties" parameter 
to "Java" tab into gitblitw.exe for override log4j configuration and start the 
service
4. Use https (and http) for access to the GitBlit web application, as you can 
see from the attached screenshot the css style is broken. If you change the 
parameter log4j.rootCategory and log4j.logger.org.apache.wicket from DEBUG to 
INFO all is done on the web pages.

Thanks and regards,
Bottone Danny

This is a bug in Jetty, not Gitblit.  You could report this upstream or update 
Jetty and see if the issue still exists.
