Typesafe activator 1.3.9 不再有效（无论版本如何）

Question

刚刚在全新的 Ubuntu 15.10 机器上下载并安装了 activator 1.3.9 for Play-Scala 2.3.8（已经安装了 jdk 8、scala 2.11.6）。

问题是activator 不再工作，我总是收到以下错误（即使是最新版本的activator）：

j3d@gonzo:~$ activator

试图删除.sbt、.ivy2...但没有办法。任何帮助将不胜感激。

好的，知道了。问题是JDK。我的 Ubuntu 盒子上安装了 OpenJDK-8……但激活器无法使用它（不要问我为什么）。最终我只是删除了 OpenJDK-8 并安装了 Oracle 的 Java 8。现在它可以工作了。
