intellij-idea - 无法创建子事件循环

Question

在IntelliJ IDEA社区版14.0.2中，我尝试运行Java Applet，并且每次尝试运行项目时，都会收到此虚拟错误。

Error: Failed to create a child event loop

我尝试过的

编译新创建的Hello World程序

更新IntelliJ

卸载并重新安装

从Windows防火墙规则允许

禁用防病毒程序

我正在将Windows 8.1与防病毒程序Windows Defender一起使用。

Answer 1

重新启动intelliJ并没有帮助，重新启动计算机就可以了!
