I have win 7 with 64-bit and wanted to utilize extra JVM heap size options, ex Xmx3g.
1) Should I install a special 64-bit JVM? I cannot find any in Java downloads.
2) Should I explicitly add some options for 64-bit run-time?
My Java control panel shows built 1.6.0).
I tried to add -Xmx3g, but it makes no difference and some Java applications show "out of memory".
