Inconsistent user experience with AppCDS

[snicoll]

Please provide a brief summary of the bug

It's not really a bug per se. The binary distributions of Adoptium do not contain the JDK base image. The OpenJDK distribution provides it out-of-the-box (as well as other vendors).

I've reproduced this with the latest LTS on MacOS: OpenJDK21U-jdk_aarch64_mac_hotspot_21.0.1_12.pkg

Please provide steps to reproduce where possible

Creating a dynamic AppCDS archive for an application can be done as follows:

/java -XX:ArchiveClassesAtExit=app-cds.jsa -jar my-app.jar

Expected Results

The app-cds.jsa archive is created or updated with that training run.

Actual Results

[0.012s][warning][cds] -XX:ArchiveClassesAtExit is unsupported when base CDS archive is not loaded. Run with -Xlog:cds for more info.

Enabling the logs provides the following:

[0.010s][info][cds] trying to map /Library/Java/JavaVirtualMachines/temurin-21.jdk/Contents/Home/lib/server/classes.jsa
