I've implemented setDTR to reset my Arduino.

This is how it works for me: 
    public void setDTR(boolean value) throws IOException {
        int SET_CONTROL_LINE_STATE=0x1;
        int DTR_HIGH =257;
        int DTR_LOW=256;
        int result = mConnection.controlTransfer(FTDI_DEVICE_OUT_REQTYPE,
                 SET_CONTROL_LINE_STATE, value?DTR_HIGH:DTR_LOW, 0 /* index */,
                 null, 0, USB_WRITE_TIMEOUT_MILLIS);

        if (result != 0) {
             throw new IOException("Setting DTR failed: result=" + result);
        }
    }
