I strictly follow the instruction on the Play framework and Boxfuse website when deploying the 2.8.x version of the the PLAY SCALA HELLO WORLD TUTORIAL application at Get Started with Lightbend Technologies | Lightbend Tech Hub.
I was using Openjdk 1.8, Scala Sdk 2.3.14, and Play framework version 2.8.7. When I deployed, I encountered the error
JVM exited with status 255
