The OperatingSystemMXBean cpuLoad beans sometimes return -1.0. Seen on Windows so far.
It is needed to investigate if it is OS limitation or VM bug. Then fix VM or update tests to accept some percentage of -1.0 .
It might be ok if bean returns -1.0 rarely, but test should find cases when OperatingSystemMXBean don't works or have VM bugs.
