Is openjdk-7-jre-headless Outdated?

[ismailsunni]

From https://github.com/r-hub/sysreqsdb/blob/master/sysreqs/java.json#L5

I to tried to install on Ubuntu Bionic inside Docker container:

root@7ad05eaa3f2f:/home/docker# apt install openjdk-7-jre-headless
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package openjdk-7-jre-headless is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'openjdk-7-jre-headless' has no installation candidate

Perhaps the alternative is https://packages.debian.org/buster/openjdk-11-jre-headless

Moreover, how is sysreqsdb handle different version of each OS?
