I wrote a simple test that just creates 500 connections to a server.
With no heap settings, I see pretty much the same heap usage as JDK 8.
With these heap settings (which are what dunit jvms use): {{-Xms512m -Xmx512m
-XX:MetaspaceSize=512m -XX:SoftRefLRUPolicyMSPerMB=1}}, I see double the heap
usage (which causes the OOME).
