>                 URL: https://issues.apache.org/jira/browse/IGNITE-5583
>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Dmitriy Pavlov
>            Assignee: Dmitriy Pavlov
>            Priority: Minor
>
> 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: http://apache-ignite-developers.2346864.n4.nabble.com/Negative-non-heap-memory-maximum-td17990.html
