Comment (by usersxx):

 Replying to [comment:2 breun]:
 > > As a meta ports, this seemed to allow other ports to just depend on
 "openjdk11" or "openjdk17", while the user could choose which actual
 implementation to install, such as "openjdk17-temurin".
 >
 > I don't think the user could actually choose which implementation to
 use, although that would be nice. Before `openjdk11` and `openjdk17` would
 just install a particular OpenJDK distribution (Eclipse Temurin on x86_64,
 Azul Zulu on arm64).

 You can just install azul zulu by using `sudo port install openjdk11-zulu`
 and `sudo port install openjdk11-zulu`. You can install eclipse temurin by
 using `sudo port install openjdk11-temurin` and `sudo port install
 openjdk17-temurin`.
