Comment # 8 on bug 1058576 from Wolfgang Bauer

I modified the package (and the start script) to explicitly require and use
Java 1.8.0 meanwhile (tvbrowser 4 doesn't support lower versions anyway).

Works fine here on Leap 42.3 with all Java 1.7.0, 1.8.0, and 9 installed (9
being the default).

I still want to test it on Tumbleweed (32bit in particular) before I submit it
though.

Feel free to give it a try too:
