ConcurrentModificationException with TableViewEditModel

[insolor]

I tried TableViewEditModel example from the TornadoFX Guide with tornadofx2, and when I try to edit a cell (double click in a cell, edit value, Enter), it throws the following exception:

When I try the same code with torndonfx 1.7.20, it works fine.
