The problem with the original example was that the value of the
--java-options is a space separated list of java arguments, not a single
java argument.
We don't know if the "bar" is a second option, or part of the value of
the first options without additional quoting like "-Dfoo='foo bar'" vs
"-Dfoo='foo' bar", or escaping.
Since the confusion could occur in several jpackage options, I do not
think it appropriate to address in the help text, but rather should be
explained more fully in user documentation.
