I can't look into this in depth immediately, but I do recall working on 
this some months back, and I'm fairly sure I resolved it for JDK 9. I 
just quickly run the test application attached to JBS-8147483 and can 
not see the cells being recreated (after the initial creation).

I will follow this up later today and will track down the relevant 
changeset (if I am right), or comment further on the issue (if I am wrong).
