Java 7中的抗锯齿发生了什么？

我有一段代码，用于获取文本并生成带有阴影效果的图标，以分配给各个组件（如下所示）。这在Java7之前一直很有效，看起来很棒，在Java7中，抗锯齿逻辑发生了一些变化，现在看起来很糟糕，而在Java6中，同样的代码看起来很棒

最后一张图片看起来还可以，所以它似乎只发生在特定的颜色组合中

无论如何，有人知道Java 7中AA的变化是什么，或者如何将其更改回去，或者使其像Java 6中那样工作吗？或者我向谁投诉违反了AA？哈哈

提前感谢您的帮助

在Java7中，反走样确实发生了变化。我现在还没有找到恢复它的方法，因为它看起来好像实际的AA代码在Java7中被更改了。所以你可以责怪甲骨文破坏了AA。我遇到的唯一解决方案是恢复到Java6（这在最新版本的OSX上是不可能的）。我希望我能帮上更多的忙，但我能想到的唯一解决方案是使用开源库中不同的AA代码。我希望这有点帮助。

检查你的VGA应用程序配置文件，如果应用程序有VGA配置文件，GPU会覆盖设置，这对我来说很好，伙计：）顺便说一句，更新你的JDK，它也可能是一个bug@user 251414-你是说当你在Java 7中运行代码时，AA看起来不错？您介意分享一下Java7中的屏幕截图吗？您使用的是什么构建？我使用的是1.7.0_25。我也尝试过使用GPU渲染设置，但这似乎并没有改变任何东西。。。谢谢你的帮助！哎呀，我很抱歉，巴迪，我好像是用JDK6运行的，我很抱歉这个错误，但你是对的，我和7有同样的问题，再次抱歉：（，但似乎有人可以解决这个问题，我没有试过是，System.setProperty（“swing.aatext”，“true”）；System.setProperty（“awt.useSystemAAFontSettings”，“lcd”）；是必需的，我已经在我的实际应用程序中设置了它们，我只是没有将它们包含在代码段中，因为这对图形对象的设置方式没有任何影响。不过，谢谢。
