>
> In org.apache.ignite.internal.managers.discovery.GridDiscoveryManager
> we can't just use getHeapMemoryUsage():
> private static final MemoryMXBean mem = ManagementFactory.getMemoryMXBean();
> mem.getHeapMemoryUsage().getCommitted();
> because of 
> https://bugs.openjdk.java.net/browse/JDK-6870537
> It should be somehow wrapped to catch IllegalArgumentException.
> Also we need to test all codebase and use wrapped version of getHeapMemoryUsage() method.
> In version 2.1 its already fixed.
