在JDK8上运行听起来不错。很难说这里到底出了什么问题。看起来您正在JDK8上运行最新的STS版本，所以一切听起来都很好。
作为一种变通方法，您可以切换回Preferences -> Spring -> Dashboard中的旧面板，但我仍然想知道为什么会出现这种异常。
另外需要注意的是，STS 3.9.1将更改欢迎面板的内部结构，因此可能会将此问题作为副作用来解决。您是否有兴趣检查它的早期版本以进行验证？如果是，请从以下位置下载STS 3.9.1的夜间版本：http://dist.springsource.com/snapshot/STS/nightly-distributions.html并尝试一下——如果这是开箱即用的，请报告。
