The Spreadsheets use a class from the info.obba.datatools package.
This class needs a network connection to run.

Hence you have to grant permission that the Java Runtime can open a network connection.
If this permission is not granted you will see an AccessViolation exception in the Java console.

To grand the permission add the following lines to your java.policy file.
Note: If you do not have a java.policy file you copy the .java.policy file into your user home folder.

The following lines have to be in your java.policy file:


grant {
    permission java.net.SocketPermission "*", "connect,accept";
};
