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.

I have the same problem anytime my Java engine is newer than Java 8 : our version of the jmol viewer works only with Java <= 8, whereas most current distros use Java >= 11. ISTR that a ticket is open about this (but I don't have the time to check it now...). EDIT : That's Trac#25026.

Workaround: use threejs (which has its own share of problems, BTW...).

Another workaround is to run the code in a Jupyter notebook. There it is the JavaScript version of Jmol that is invoked, note the Java one, and it works (tested with Ubuntu 18.04).

This bug is another motivation for #22408. @Emmanuel_Charpentier: which "own share of problems" has threejs, given the recent improvements?

I'd also like to know what outstanding major problems there are with the Three.js viewer. Please add them to #22408 at your convenience.

@ericg, @paulmasson: see my comment in the ticket.

Thanks! That explains why it was stuck indeed. I did create a dummy worksheet to execute my snippet of code and jsmol does work inside jupyter notebooks.
