Javafx应用程序吃太多内存

Question

我正在使用java profiler测试我的应用程序。在Telemetry配置文件下，我注意到它使用了太多的内存，我虽然这是我的项目中的类，所以我做了一个object配置文件，并意识到它不是我的对象，实际上是最高的对象只消耗了6400B，然后我测试了我项目中的所有对象并且意识到byte[]正在升级到130,000,000B但是我的程序无所事事，什么都不做，我哪里出错了？这是我的JavaFx Main Class的一部分

    this.lblNumber.setMaxWidth(Double.MAX_VALUE);

    fadeInImageSettings.setAutoReverse(false);

    */
    this.sldRotate.setValue(0);
    this.sldScale.setValue(1);
    this.anchorImageSettings.setVisible(false);
 }

以下是内存使用If I leave the app for a longtime its shooting to up to a GB
