java - 在 GWT 2.7 super 开发模式下调试，stackTrace 丢失？

Question

我刚刚从 GWT 2.5.1 迁移到 2.7，并且是第一次使用 SuperDev 模式。我在 Chrome 开发工具中启用了“JavaScript source maps”。在 Chrome 控制台中，异常如下所示:

com.google.gwt.event.shared.UmbrellaException: Exception caught: For input string: "a"
  at fillInStackTrace_0_g$
  at Throwable_3_g$
  at Exception_3_g$
  at RuntimeException_3_g$

  at dispatchEvent_4_g$
  at dispatchEvent_6_g$
  at apply_0_g$
  at entry0_0_g$
  at <anonymous>

OnModuleLoad 我正在捕获异常:

GWT.setUncaughtExceptionHandler(new GWT.UncaughtExceptionHandler() {
        @Override
        public void onUncaughtException(Throwable e) {
            GWT.log(e);
        }
    });

如何获取堆栈跟踪？我试过这样的事情 https://stackoverflow.com/a/24334132/1660637但无法工作。

您是否尝试将这些添加到您的 gwt.xml 文件中？

<set-property name="compiler.stackMode" value="emulated"/>
<set-configuration-property name="compiler.emulatedStack.recordLineNumbers" value="true"/>
<set-configuration-property name="compiler.emulatedStack.recordFileNames" value="true"/>
