Subject: [PATCH] Use --release 8 during compilation

Motivation:

We should use --release 8 during compilation to ensure we always end up
with the correct java version that is required.

Modifications:

- Upgrade compiler plugin so the release flag is only used when
compiling with java9+
- Specify release flag
- Fix source and target version as we already use JDK8 classes in the code.

Result:

Always end up with the correct bytecode
