Update VM used by virtual-device to Java 11 #38

Closed diegorondini closed 9 months ago

diegorondini commented 9 months ago

Since we are building with JDK 11: https://github.com/eclipse/hara-ddiclient/commit/cd041b6bbdf6925b88e044738af451a880e3dc51

the virtual device docker container no longer runs with JDK 8:

$ docker run hara-virtual-device:2.0.0
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/eclipse/hara/ddiclient/virtualdevice/MainKt has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
