Only if the `$JAVA_HOME/jmods` folder is also added to the module path. Existing behaviour is like this:


bin/jlink --add-modules ALL-MODULE-PATH --module-path mods --limit-modules jdk.net --verbose --output test-img
Error: Module jdk.net not found
java.lang.module.FindException: Module jdk.net not found

vs.


$ ./bin/jlink --add-modules ALL-MODULE-PATH --module-path mods:$(pwd)/jmods --limit-modules jdk.net --verbose --output test-img
java.base file:///disk/openjdk/builds/oracle-ea/jdk-24+26/jmods/java.base.jmod
jdk.net file:///disk/openjdk/builds/oracle-ea/jdk-24+26/jmods/jdk.net.jmod

Providers:
  java.base provides java.nio.file.spi.FileSystemProvider used by java.base


I can revert those changes if you prefer.
