New version of Play not working?

[Rob Guinness]

I've just returned to Play after a long pause. I downloaded the newest version (2.5.8). I created a new application by running:

activator new my-first-app play-java

Then, I started it by running:

activator run

Everything looked fine, until I visited localhost:9000 in my browser. I get the following exception:

I am using OpenJDK 8. From the Play website, it was not clear if the latest version supports OpenJDK. Here are the details:

$ java -version
openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

Please advise.

StringConcatFactory isn't even a class in JDK8.

I also created a new play project, like you did and actually everything worked.
