Problem:

Stack dumps occur on console while trying to select a file with the JAWS screen reader enabled.

Environment:

Windows 7
JAWS screen reader
FMW Upgrade Assistant

How to reproduce:

1. Install wls_jrf_generic.jar on Windows 7

2. Start the JAWS screen reader

3. Start the Upgrade Assistant (located within ship home at \oracle_common\upgrade\bin). CD to that folder and type the command "ua"

4. A "Welcome" screen will display, click the Next button

5. A "Schemas" page will display. Click the radio button named "Weblogic Component Configurations". A input field with a Browse button will appear.

6. Click the "Browse" button. When the dialog pops up, click on the "Location" pulldown and select the folder named "oracle" which is two levels up in the hierarchy. Then click the "Open" button. This will cause the first stack dump to appear on the console.
