I'm assuming you're wondering about heap size. D:\>\jrockits\harmony-hdk-r487452\jdk\bin\java -Xms1m Hello [ERROR] Specified initial heap size (1 MB) is less than the minimum required initial heap size (8 MB). HMYEXEL062E Internal VM error: Failed to create Java VM FAILED to invoke JVM.
D:\>\jrockits\harmony-hdk-r487452\jdk\bin\java -Xms8m Hello Hello, World! Looks like 8M is the minimum we require. Remember that JRockit is primarily a server-side JVM. Most of our users run with gigabyte sized heaps, with the max amount tested being 3.5 TB (!).
