Hudson build always ends in "java.lang.OutOfMemoryError: Java heap space" error

Question

I had a problem with a Hudson build Windows XP slave 4 GB of RAM and in the batch file to call JNLP I indicated the following:

javaws -J-Xms1280m -J-Xmx1024m http://hudson-master.domain.com:8080/computer/Exige/slave-agent.jnlp

Why can't I give it more than 1 GB?

any help and suggestion would be very helpful.

Thanks AWT
