But I'm using Java 17:

java -version
openjdk version "17.0.19" 2026-04-21
OpenJDK Runtime Environment Homebrew (build 17.0.19+0)
OpenJDK 64-Bit Server VM Homebrew (build 17.0.19+0, mixed mode, sharing)

The build doesn't run at all on Java 8:

CI=true mvn clean verify \
    -P docker \
    -Ddocker-maven-plugin.version=0.48.1
Unrecognized option: --add-exports
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

java -version
java version "1.8.0_471"
Java(TM) SE Runtime Environment (build 1.8.0_471-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.471-b09, mixed mode)
