[jitter] Homing in on the problem

Hi again.

I have got a little close to what might be the problem. There's a memory leak occurring in a Java external that I'm using: it appears to be caused by creating a new JitterMatrix object on each bang. I'm looking for alternative ways around this, but here's the code in case anyone can offer suggestions: as you might gather, the number of 'particles' that I'm dealing with is increasing over time up to a maximum of (totalparticles), but the memory usage keeps increasing even after this point is reached.

public void bang()
	{
		utilcounter++;
		if (totalParticles < maxParticles -1 && (utilcounter % 4 == 0)) {
			particle[totalParticles] = new Particle(mouseX,mouseY,totalParticles,1.);
			totalParticles++;
			counter++;
		}

		double[] xlocs = new double[totalParticles];
		double[] ylocs = new double[totalParticles];
		double[] zlocs = new double[totalParticles];
		
		for (int i=0;i<totalParticles;i++) {
			//charges
			particle[i].field();
			//friction
			particle[i].xv *= momentum;
			particle[i].yv *= momentum;
			//gravity
			particle[i].applyGravity();
			//update position
			particle[i].move();

			//fill arrays for matrix
			xlocs[i] = particle[i].x;
			ylocs[i] = particle[i].y;
			zlocs[i] = 0.0;
			
		}
		jm = new JitterMatrix(3,"float64",totalParticles); // THIS LINE CAUSES A MEMORY LEAK!

		jm.copyArrayToVectorPlanar(0,0,null,xlocs,totalParticles,0);
		jm.copyArrayToVectorPlanar(1,0,null,ylocs,totalParticles,0);
		jm.copyArrayToVectorPlanar(2,0,null,zlocs,totalParticles,0);
		outlet(0,"jit_matrix",jm.getName());
		
	}
