# jmol stuck at "Initializing 3D display"

I have a freshly compiled version of sage 8.9.rc0. jmol used to work fine until I got it stuck at "Initializing 3D display"

```
sage: h = polytopes.regular_polygon(6)
sage: w = h.wedge(h.facets()[0])
sage: w.plot()
Launched jmol viewer for Graphics3d Object
```

The pop out window opens and then is stuck for eternity. This is annoying. I know that I could use a different viewer like `threejs`

but it does not open a window in my browser (which is another unrelated issue). So I would really like jmol to just work as I expect it to...

(I also upgraded my debian from stretch to buster, but I do not think it is the problem since jmol starts fine outside of sage)

How to fix this?

Same issue with Ubuntu 18.04 (OpenJDK 11.0.4).

For the record, the issue is fixed in SageMath 8.9, thanks to the update of Jmol performed in #25026.
