It turns out to be more complicated than using a flag ... in fact that flag
only exists on OSX. So for 64bit windows:

A) either download and install the 32bit JVM (that will work fine, and you
can use the provided libsbml libraries) or
B) generate 64bit java bindings. That is a bit harder than anticipated, but
not overly so, you will need to compile libsbml
For yourself, next generate the SWIG bindings for Java, and then slightly
alter the existing visual project file to no longer target x86 but
x64. Here the details:

Building and installing libSBML
http://sbml.org/Software/libSBML/docs/cpp-api/libsbml-installation.html

Enable a 64-Bit Visual C++ Toolset at the Command Line
http://msdn.microsoft.com/en-us/library/x4d2c09s.aspx

Configure Visual C++ Projects to Target 64-Bit Platforms
http://msdn.microsoft.com/en-us/library/9yb4317s.aspx

In the long run it might probably make sense to add a feature request that
the Java bindings are built for 64bit Java as well.

Cheers
Frank
