问题 We have recently upgraded our banking application from java 1.6 to 1.8 and jboss 4.x to wildfly 10.1. We have observed that java consuming all the cores (10), available on the machine. Can someone tell what is the reason, normally with jboss 4.x max CPU utilisation was up to 4 cores. Do i need to configure anything for Garbage collection?
