Adam, Yes for now Java 8 is what is fully supported.
Hopefully the remaining issues can be resolved in the not too distant future to become compatible with Java 9+. I know in the HBase case it requires changing to a newer version of the client because the 1.1.2 client has the code that caused the issue you ran into with "Unexpected version format: 10.0.1".
