The jdk.vm.ci.common.InitTimer[1] was introduced when tuning the initialization cost of JVMCI and Graal. However, since the introduction of libgraal, the initialization cost is now so low (between 1 and 2 ms) and jargraal is a development only option that this code is no longer necessary and should be removed.
