On Debian Sid I use Azul JDKs (Zulu 8 and Zulu 9) because they provide
a deb repository and it is easy. On Fedora Rawhide I use the Fedora
provided OpenJDK, Azul do not provide a Fedora rawhide rpm repository,
but they do provide a RHEL/CentOS one. Why not the Debian provided
OpenJDK and ignore Azul? It comes down to being told Debian Sid OpenJDK
was unreliable and that I should trust Azul.

I have discovered some incompatibilities of Groovy 2.4.14 running on
Zulu 8 compared to Zulu 9. I have yet to try on Fedora OpenJDK to see
if it is an Azul problem or a Groovy problem.

I am not about to use OracleJDK ever again.

Obviously though I am always using the free versions, I do not pay a
licence fee.
