  * - Not Significant: A non-zero %Diff for the mean could be noise. If the
      %Diff is 0, an actual difference may still exist. In either case, more
      samples would be needed to detect an actual difference in sample means.

Changes for 6891435, 6946559 and 6987967 should be included into the forward-port.
Changes in deploy ws (fixes for 6867515 and 6888203) are already forward-ported (plugin always adds awt.warmup property)
