AppleCommander @1.8.0: missing required Java version

AppleCommander fails to build if Java is not installed:

It succeeds if, for example, the openjdk11 port is installed.

The port already includes the java 1.0 portgroup. What else must I do to get this port to use a MacPorts Java, if a system Java is not already installed?

I updated AppleCommander to 1.8.0 which now requires Java 11 or later so I added this to the Portfile:

java.version        11

Then the ​build failed with:

DEBUG: java-portgroup: Trying to find JVM version: 11
DEBUG: java-portgroup: Detected JVMs: 17 /opt/local/Library/Java/JavaVirtualMachines/openjdk17-zulu/Contents/Home
DEBUG: Discovered JAVA_HOME via /usr/libexec/java_home: /opt/local/Library/Java/JavaVirtualMachines/openjdk17-zulu/Contents/Home
DEBUG: Adding dependency on JDK fallback openjdk17-zulu
Error: AppleCommander requires Java 11 but no such installation could be found.
Error: Failed to fetch AppleCommander: missing required Java version

This led me to think that what I specified above was unintentionally an exact version requirement. While I think it's weird that the java portgroup installed a version different from the one I said I needed, and then complained about it, I changed it, hopefully, to allow the use of Java 11 or later:

java.version        11+

But this then ​failed to build with:

DEBUG: java-portgroup: Trying to find JVM version: 11+
DEBUG: No value for java JAVA_HOME was automatically discovered
DEBUG: Adding dependency on JDK fallback openjdk17-zulu
Error: AppleCommander requires Java 11+ but no such installation could be found.
Error: Failed to fetch AppleCommander: missing required Java version

Evidently I have no idea how to use the java portgroup.
