It seems to me that all the command line options of the VM before jigsaw doesn't use space as a separator, but with the new option like --module-path or --add-modules, you have to put a space after, so it doesn't work well with the -J option used to take option from tools like javac to feed them to the VM, because the space in the middle of the VM option is interpreted as a space between the options of the tool.
