Why is JTable scrolling taking so much memory?
@Override
public void run() {
        while (true) {
            jScrollPane1.repaint();
            jScrollPane2.repaint();
            try {
                this.sleep(10);
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
        }
    }

@Override
public void run() {
    while (true) {
        aLabel.setText("Memory consumption: " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory());
        try {
            this.sleep(200);
        } catch (InterruptedException ex) {
            ex.printStackTrace();
        }
    }
}
