Java 11 目前，Play主要支持Java11.所有模块和示例都已经在使用Java进行了测试.我们甚至还可以使用Java 11来构建Play本身，只有一个需要解决的已知问题与ssl-config有关.

Java 11 At this point, Play mostly supports Java 11. All the modules and samples are already being tested using Java; we even have Play itself building with Java 11, there is only a know issue we need to solve, related to ssl-config.

根据上面的链接，Play将自2.8开始正式支持Java 11.

According to the link above, Play will officially support Java 11 since 2.8.
