This has come up while analyzing JDK-8277437.

The accessibility implementation of the virtualized controls make use of a method named - VirtualFlow.getPrivateCell(int) to get access to the cell.
This method was specifically added to the VirtualFlow class as part of JDK-8096601 and used in ListView as part of JDK-8095859 to improve accessibility.

This bug is to -
1) Review the current accessibility design of virtualized controls - particularly the VirtualFlow.getPrivateCell(int) method - as it mutates some of the data structures which are used in VirtualFlow.layoutChildren() method.
2) Possible cleanup and re-write accessibility implementation of virtualized controls
