Ignored exception: java.lang.IllegalArgumentException: white space not allowed
我相信错误是由试图获得与在 Applet的的的getImage（）方法的形象造成类。这是code：
I believe the error was caused by trying to get an image with the getImage() method in the Applet class. This is the code:
try {
image = new ImageIcon(main.getImage(main.getCodeBase(), imageName + ".png"));
} catch (Exception e) {
e.printStackTrace();
}
有关参考，下面是我使用的HTML标签：
For reference, here's the tag I'm using in the HTML:
＆LT;小程序归档=https://github.com/nrubin29/FreeFall-Applets/blob/master/Noah/Noah.war?raw=truecode =FreeFallMain ＆GT;＆LT; /小程序＆GT;
如果你想看到错误自己，只是去 HTTP：//nrubin29.github。 IO /自由落体小程序/
If you want to see the error for yourself, just go to http://nrubin29.github.io/FreeFall-Applets/
谢谢！
推荐答案
如果您使用的是Java 8，它看起来像有解决这个具体的行为开放的bug：
If you're using Java 8, it looks like there's an open bug around this exact behavior:
<一个href=\"https://bugs.openjdk.java.net/browse/JDK-8042622?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel\">https://bugs.openjdk.java.net/browse/JDK-8042622?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel
在本质上，这个错误是，它是在Java核心的bug，并没有什么可以做可以修复它。所以你必须要等待的Java 8u40（如果修订实际会达到他们的目标释放）。
In essence, the bug is that it's a core bug in Java, and nothing you can do can fix it. So you'll have to wait for Java 8u40 (if the fix actually hits their target release).
