        Description

        On Linux kernels 2.6 and later, the JDK would include time spent waiting for IO completion as "CPU usage". During periods of heavy IO activity, this could result in misleadingly high values reported as CPU consumption in various tools like Flight Recorder and performance counters. This issue has been resolved.
