I agree it's a little bit awkward, unfortunately we cannot look at the quotation as that had been decoded by shell.

Just take next token as value would be simpler, see the origin PR from @YaSuenag at https://github.com/openjdk/jdk/pull/19987.

The other alternative would be that, we can check next token against known options of jlink, and treat it as value without match. That would limited the potential ambiguous conflicts but would be even more mysterious to user?
