Question

Jetty显示ttf和woff文件的奇怪行为。访问.ttf文件（静态）时会生成下面的堆栈跟踪。我将文件重命名为.bin，工作正常。然后我创建了一个常规的html文件并用.ttf扩展名保存，出现了同样的问题。

ubuntu上的java版“1.7.0_03”+ jetty-9.0.0.M3。

完整堆栈跟踪：

Jetty缺少mime.properties中的默认mime类型条目。我刚刚为jetty9解决了这个问题。快速解决方法是在webdefault.xml中为ttf添加mime类型：

TTF 应用/八位字节流

干杯，托马斯

Jetty 9将空指针抛出一定的扩展名（woff ttf）
