I am using jetty-9.2.2 with CometD-3.0.1. I am seeing below warning in my setup. It comes ~4,5 times in a day.: 

2014-08-28 08:50:53.712:WARN:oejh.HttpParser:qtp607635164-15194: badMessage: 
    400 Illegal character for HttpChannelOverHttp@5946f125{r=1,a=IDLE,uri=-}

There is no details that can be debugged from the warning message. I have already logged a request https://bugs.eclipse.org/bugs/show_bug.cgi?id=443049 to provide detailed warning.

Meanwhile I want to know what is causing this warning? Can I ignore this or some messages are lost because of this?

Change https to http in the url.

I had the same error, then found out it's because my application did not support https, so jetty cannot recognize the https encrypted request.
