JAVA invalid maximum heap size. The specified size exceeds the maximum representable size

I have to run this command to fix the code to a xml file:

java -Xmx5G -cp .:jsoup-1.8.2.jar CheckSyntax test.xml > test2.xml 

But it gives me this error:

Invalid maximum heap size: -Xmx5G The specified size exceeds the maximum representable size. 

How can I make it work?

If your JVM is 32-bit you cannot use the switch -d64

java -Xmx2G -cp .:jsoup-1.8.2.jar CheckSyntax test.xml > test2.xml 

32 bit java cant use heapsize > 2G

Here is the link to get Java 64bit to allow a larger heap-size. Just select the "Windows Offline (64-bit)" option.
