Dmitriy Pavlov updated IGNITE-5583:
-----------------------------------
Description:
On jdk 1.8.0_131 there is negative amount of maximum non heap memory returned
by following code:
ManagementFactory.getMemoryMXBean().getNonHeapMemoryUsage().getMax());
returns -1.
And this value is used in ignite metrics in
GridLocalMetrics.getNonHeapMemoryMaximum() which becomes negative.
It is required to switch non-heap memory metrics to new page memory semantics,
this should show a clean picture in the node output and will also protect us
from ambiguous -1 output.
See also discussion here:
