Hi,

I have update my project from scala 2.11.6 to 2.12.4. In order to make it work I also had to update gatling from 2.1.7 to 2.2.4. I fixed all compilation errors and deprecations and feature warnings.

However now, I have the error java.lang.NumberFormatException: Not a version: 9 throw by gatling which I have no clue what is the cause (I'm not using java 1.9 but java 1.8.0_162)

Does anyone could have a clue of what means this error? Thanks

You're using Java 9, not Java 8. Really.

And Gatling 2.2 was targeting Scala 2.11, not 2.12. You'd need latest Gatling 2.3.1.

It looks like you hit this error: https://github.com/scala-js/scala-js/issues/2798
There is a fix in that issue.

No really. Gatling 2.3 doesn't support Java 9 because of the ClassLoader changes. Gatling 3 does. Period.

The NumberFormatException because somewhere someone tries to parse the java.version System property and that it crashes on the "9" value that doesn't look like previous pattern ("1.5", "1.6", "1.7", "1.8").

David Prévost is actually using Java 9 and not Java 8, 100% sure.

I'm not sure how my project can use Java 9, I do not want Java 1.9. I referencing to Java 1.8 in both maven and IntelliJ (which I also use with my scala project)
