I assumes it has to do with that Java's memory need to be contiguous
and that something small just get in above the 2 GB mark.

64 bit !!

3GB swich gives contigous 3GB memory to user address space.
Basically in Windows 32 bit, of 4B - 2GB (contigous) is accessible by
kernel and other 2GB by user address space. With 3GB switch, kernel
uses only 1GB, so user address space has more memory (up to 3GB). This
is a soltion to provide more memory if one cannot switch to 64bit
which is the best solution.

I have used this feature in conjunction with Oracle. It does not
require any changes in one's
program. I will be really surprised if Java or any other application
cannot use it.

I know what /3GB does.

Read what I write.

Java can not use that extra GB.

I guess it is because something else it putting something
in around the 2 GB mark.

Thanks. I am curious where it is documented it cannot use more than
2GB even when /3GB switch is on, just asking.
