While looking to compile OpenJDK from source, the newest General Availability version (OpenJDK 10.0.1) insists on OpenJDK 9 or 10. JDK 11, however, is not due to be released until September 2018.
However, to my surprise, when I do
apt search openjdk the result is:
... openjdk-11-jdk - OpenJDK Development Kit (JDK) ... openjdk-8-jdk - OpenJDK Development Kit (JDK) ...
No OpenJDK 9 or 10!
And wait, is that OpenJDK 11? Maybe a Beta release? Nooo….
So I looked at
apt show openjdk-11-jdk:
Package: openjdk-11-jdk Version: 10.0.1+10-3ubuntu1 ...
Why has OpenJDK 10 been packaged as openjdk-11-*??
