This is what my system shows with my Java hello world program: - $ java -Xmx500M Hello Hello from Java - $ java -version java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing) - $ cat /proc/version Linux version 2.6.32.16-141.fc12.i686.PAE (mockbuild@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx) (gcc version 4.4.4 20100630 (Red Hat 4.4.4-10) (GCC) ) #1 SMP Wed Jul 7 04:41:17 UTC 2010 - $ cat /proc/meminfo MemTotal: 1017560 kB ... SwapTotal: 2048752 kB As you can see, your command works on my laptop, a Thinkpad R61i with 1GB RAM and 2GB swap space running Fedora 12 and Sun Java SE 6. Martin
