宽度（-1）和高度（-1）不能<= 0

总是收到在处理一些奇怪的错误，使用以下的微小的一段代码：宽度（-1）和高度（-1）不能<= 0

void setup() { 
    size(200,200); 
} 

void draw() { 
    background(0); 
    loadPixels(); 
    updatePixels(); 
}

错误：（含堆栈跟踪）

现在起初我以为这是一个bug，因为之前有另一个bug在我重新启动Processing时消失了。它似乎仍然没有很好的Mac OS X Lion支持（这就是我正在使用的）。但是我尝试了稳定版本和预发行版本，两者都有相同的错误。有没有人得到这个？有谁知道如何修理它？我是否需要安装更好的JDK或其他？

请显示异常的堆栈跟踪。 – 2011-12-26 17:41:31

当然，添加了堆栈跟踪。 – slartibartfast 2011-12-26 17:47:35

“背景”，“loadPixels”和“updatePixels”是做什么的？如果你能向我们展示一个简短但完整的程序来证明问题，这将有所帮助。 – 2011-12-26 17:56:19
