【问题描述】：
更新java版本（1.8.0_66）后不久
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
通过激活器创建新的 play-scala 应用时，我不断收到以下错误！

我不确定原因。我尝试重新安装 playframework 但没有运气。我在这里错过了什么吗？
【问题讨论】：
-
我注意到你正在使用 scala 酸洗。您是否有机会使用不同版本的 Java 生成 unpickler？
-
不知道！创建新项目时，类型安全/播放会自动生成这些序列化程序吗？ .事实上，我尝试使用默认模板（'play-scala'）创建一个新项目，结果是一样的。不确定是否有任何错误配置。
