Goal

• As RHEL user I want to install Ant, but I don't care what Java
  runtime it uses, as long as it works. I expect "dnf install ant" to
  just work.

• As RHEL user I want to install and use Ant, but I don't know which
  Java runtime it should use. I want to rely on the default
  configuration recommended by the RHEL creators.

• As RHEL user I want to install Ant and run it with a specific
  OpenJDK version that is packaged in RHEL. I expect Red Hat support,
  as long as OpenJDK version chosen is supported.

Acceptance Criteria

• dnf install ant installs Ant configured to run with default system Java version (currently OpenJDK 17)
• dnf install ant-openjdk${n} installs Ant configured to run with OpenJDK $n, for n in 8,11,17,21
