Is it normal for a springframework application to take over 400% of the CPU (determined with top) in Linux (Centos 7)? Consultants have deployed a couple of web apps in our Wildfly 10.1 (JDK1.8.x) and each one of four threads from these deployments are taking 100% CPU. I have never seen such high CPU usage in a Linux server with JBoss (4-7) and Wildfly (10.1). It looks like these four threads are created from the initializer of the springframework and they never surrender any CPU time to the rest of the server.
