I've been watching the development of Terdata Studio for several years now, and have been very impressed in all the progress that's been made. I recently downloaded the latest release, 16.20.09, and was a little surprised to find that it required JRE 10.
This was a little surprising to me since Java 10 is not a long-term support release and Oracle says it has reached the end of its support. And it was a little sad since JRE 10 is not a LTS version, my company does not have immediate plans to enable it on our machines.
I don't know if the new release requires new features in Java 10. If not, I'd ask to stay with 8. I believe that Java 12 is the next LTS version, but it's not yet released.
I've just heard there will a version of Teradata Stuido that is compatible with Java 8; I'm told it should be released in the next few weeks.
Happy New Year's!
