I have a test consuming quite a lot of memory and seems to be only

System.out.println("The test only runs on server VMs");
return;
}
Is there a better way to detect it?
Searching for contains("Server") would be less error-prone as the above
will not work on 64-bit. But there is a better property to use:
sun.management.compiler
which will report eg "Hotspot Client Compiler". However, these days both
properties might report Tiered rather than Server. Also for -Xint
sun.management.compiler doesn't exist.
That all said this seems like the wrong solution to the problem. Amount
of memory used shouldn't be that dependent on client vs. server VM
