I can confirm that this fixes every remaining issue related to ListView to my knowledge.

My test application (which was an extended version of the test in this ticket: https://bugs.openjdk.org/browse/JDK-8277785) works now 100% correctly.

The application at Zeiss works now without any ListView-related workaround.

So, on my side - with this fix, all ListView issues known to me are fixed.
