> Hello @Glavo, I see you reopened this PR, so I'm guessing you are still interested in pursuing this further. Are you considering updating this PR to implement Alan's suggestion to do similar changes in `JImageTask.java` and `JlinkTask.java` to use `Locale.ROOT` or update this proposed change to use `Locale.ENGLISH`?

@jaikiran Hi Jaikiran, as my previous reply, I do not agree that `Locale.ENGLISH` should be used here, I think `Locale.ROOT` is more reasonable.
