I just committed a change to develop which catches the
IllegalStateException caused by JDK-8207200 when the StatSampler samples
JVM memory usage using MemoryMXBean.
commit 1143af997292df0f6d480084ffd2103fa2c17bbf (origin/develop,
origin/HEAD)

GEODE-6253: Handle JDK-8207200 gracefully in VM stats
The above change prevents the following, so please don't add any more
IgnoredExceptions to dunit tests for this:
[fatal 2019/01/04 00:15:19.050 UTC <StatSampler> tid=67] committed =
538968064 should be < max = 536870912
java.lang.IllegalArgumentException: committed = 538968064 should be <
max = 536870912
