I just solved this another way, because no amount of quoting or spaces in any of these examples worked for me.

1 Detect if the file URI has a anchor or query string

2 If so, create a temp file File tmpfile = File.createTempFile("apphelp", ".html") with a meta-redirect to the actual file URI I desire:

Runtime.getRuntime().exec(
  "rundll32 url.dll,FileProtocolHandler \"" 
  +tmpfile.toURI().toString()+ "\"");
