FWIW DataNucleus v6.0 moved to supporting Java 11+
Hi Craig,
I think your JDK version is too old. I downloaded jdk-8u71, installed it and
see the same errors.
When I use jdk-8u201 everything compiles and runs fine.
Any reason why you are using such an old Java 8 version?
I switched to openjdk from adoptOpenJDK or from Azul (Zulu).
Regards Micha
I had installed the new java 8 version u333 but it looks like I just installed
a jre.
So now I have a proper jdk 8u331. And the most recent maven 3.8.6.
