具体地说

```java
Caused by: java.lang.IllegalArgumentException: URL must not be empty
	at javafx.graphics/javafx.scene.image.Image.validateUrl(Image.java:1084)
	at javafx.graphics/javafx.scene.image.Image.<init>(Image.java:688)

要么删除第38行的<Image>元素,要么为其Image指定有效的URL。

Either remove the &lt;Image&gt; element on line 38, or specify a valid URL for its Image.
