(dependency) - upgraded JUnit and jackson
Upgraded the dependencies in pom.xml and build.gradle.
Also followed the suggestion to re-write the deprecated task to task.register.
Closes #353
Thanks for taking care of this! I have dependabot configured, and it should have told us about this, but it looks like the alerting rules had been broken somehow. I've fixed that now, I hope.
The build fails in some cases, I see. I can look into that later.
Once dependabot works, you can reject this PR.
@larsga In build.gradle, the Java source and target are specified as
sourceCompatibility = 11
targetCompatibility = 11
Why does the build matrix include OracleJDK / OpenJDK 8, 9 and/or 10 ? They all fail.
Should the above config be chanegd to = 8 for both source and target compatibility ?
