Obviously this is not a problem of the Dashboard but of your Java setup.
The Dashboard is working with Java 1.7 as well as with Java 1.8.
You probably will have the same problem with every other self-executing jar archive.
Please try the following: Call from the Dashbaord.app folder (e.g. C:\Murlengine\Dashboard.app>):
"%JAVA_HOME%\bin\java.exe" -jar dashboard.jar
This should work.
To permanently fix the problem please uninstall all of your Java JDKs and reinstall with the installer from Oracle.
Please let us know if that fixed your problem.
Thanks and br,
