Correction: mac: 1069416448 rhel: 954466304
One difference between the two,
on my mac somehow UseConcMarkSweepGC is enabled as default and on rhel it is
not. If I add
{noformat}
<jvmarg line="-XX:+UseConcMarkSweepGC"/>
{noformat}
inside the build.xml, then this test passes. But the return value of
Runtime.getRuntime().maxMemory() is still a bit different (1060372480).
Is there a better way to test this method without going through this system
call?
