Jar classpath issue on windows

When I jarify the sample project and run it I get:
C:\projects\fxmltableview>jrubyfx-jarify.bat src --main src/FXMLTableView.rb dist/FXMLTableView.jar
C:\projects\fxmltableview>java -jar dist\FXMLTableView.jar

It looks like that classpath is getting mangled but I'm not sure what it's supposed to be.
Can anyone offer insight?
TIA

@monkeysuffrage , I just posted three issues that I encountered while trying to jarify the Demo. The workarounds I mention combined to allow me to successfully make and execute a jar for the Demo. One of the issues involves a LoadError very similar to the one you mention; they are quite possibly related. It would be helpful to know if the workarounds work for you as well.
