> After Undertow included https forwarding features when shipped with Wildfly CR1, we experienced high cpu load on our machines, reproduced on 5 different servers. Up to 3 threads are running wild, sometimes it's just one thread though. On the forum reference there are screenshots from jconsole including stacktraces of the threads.
