Blank page when opening demo url

[riverdusty]

Windows 10 x64, with virtualbox, etc.

When I navigate to the url provided in the documentation (http://demo_josso_1.josso.dev.docker:8081/atricore-console) I get a warning about running flash (which the documentation doesn't cover) but after allowing flash I get a blank page. Rebooting, reloading page, redoing the entire tutorial from scratch, still a blank page.

Adding index.jsp at the end causes a Java error, org.apache.jasper.JasperException: Unable to compile class for JSP
