This isn't intended behavior; nothing in Oracle documentation states this limitation, and moreover the command itself gives opaque response: there's no error message or non-zero exit, instead the command does nothing and no modules are changed after hashing.

The conflicts are due to later commits being backported first; as all main `HashesTest.java` patches on jdk17 are now backport to 11, resolution meant simply copying 17's implementation over (some differences remain like `upgradeableModule` method is in different location but otherwise its function is exactly the same). This change was ran on internal Amazon pipelines and passes jtreg tier1-4 + tck tests on the following platforms: linux x64, aarch64, x86, aarch32; macos x64, aarch64; windows x64, x86.
