To Reproduce:

1. Run the HelloTableView Demo
2. Select a middle row from the table

I was on Row 4,

3. Pressed CTRL-Up arrow
4. Tried to change focus / selection to few rows and the demo exited

Noticed the following on the command window

[TablePosition [ row: 4, column: null, tableView: TableView@34d0412f[styleClass=
table-view] ]]


[TablePosition [ row: 2, column: null, tableView: TableView@34d0412f[styleClass=
table-view] ]]


[TablePosition [ row: 1, column: null, tableView: TableView@34d0412f[styleClass=
table-view] ]]


[TablePosition [ row: 0, column: null, tableView: TableView@34d0412f[styleClass=
table-view] ]]


[TablePosition [ row: 1, column: null, tableView: TableView@34d0412f[styleClass=
table-view] ]]

Similar issue happens with CTRL-Down arrow too

This issue specific to JAWS and always reproducible. Win 7 + Narrator works Ok, and is also working ok without any screen reader.

Expected:

CTRL-Up - Move focus up without changing selection
CTRL-Down - Move focus down without changing selection

Actual:

app quits / exits. Also reproducible with Ensemble demo
