Oh, you probably need commercial repos in ubuntu now.  Oracle (anything) is technically not free.  At best it wants your soul, at worst it wants cash, as oracle jre 9 wants cash to use it from developers.  Which only hastens its death unless that's all a developer knows.  Everyone in India learns it as a second language since 1999, it's the only reason it still exists.

Again OpenJDK and OracleJRE are totally different - including version numbers.  If someone says "works with Java 8", they 99.9% of the time mean OracleJRE and their versions, and theirs only.

OpenJDK is only ever used with, well, I don't even know anymore, as everyone Open Source moved on to hate Java, Oracle, Larry Ellison, etc.  You can pretty safely remove/forget OpenJDK as an end-user at this point I think, unless something specifically mentions needing it.

Thanks for the tip!
