jit.convolve within Java?

Is it possible to make use of jit.convolve within a Java context? I believe that it should be possible to set the convolution kernel as in the example below, but when I retrieve the “in2_name” attribute it comes back as null, even after explicitly setting it.


import com.cycling74.jitter.JitterMatrix;
import com.cycling74.jitter.JitterObject;
import com.cycling74.max.Atom;
import com.cycling74.max.MaxObject;

public class Test extends MaxObject
{
private JitterObject conv;
private JitterMatrix kernel;

public Test( int width, int height )
{
// declare convolution kernel
kernel = new JitterMatrix( 1, "float32", 3, 3 );
kernel.setcell2d( 1, 0, new float[] { 1.f } );
post( "my kernel: " + kernel.getName() );

// create jit.convolve and set kernel
conv = new JitterObject( "jit.convolve" );

post( "BEFORE default kernel: " + conv.getAttr( "in2_name" ) );
conv.setAttr( "in2_name", kernel.getName() );
post( "AFTER explicit kernel: " + conv.getAttr( "in2_name" ) );
}

public void notifyDeleted()
{
conv.freePeer();
kernel.freePeer();
}
}
