Re: [jetty-users] Jetty client 100% CPU
Hi Simone,

Few days ago I started a mail thread "Jetty 9.1.2 in OSGi". I still cannot make Jetty 9.1 run in OSGi because of problems with dependency resolution. So, probably I will have to try harder and find a way. I wish I had no OSGi in my system.

Thanks for help.

I think this spin was fixed in 9.1.x.
Can you please try the staged 9.1.3 ?
