Browsers Tested: Ie8/IE9 and FF3.6

It has been noticed that under different scenarios different "Application Error" dialog is showing up by clicking on the "Error : click for details"
Most of the negative scenarios are showing "Application Error" dialog with "OK" and "Details" button. But sometimes when we click on "Error : click for details" we are seeing 2 different dialogs
1) With "Details" and "Ignore" Button
2) With "Details", "Reload" and "Ignore" Button. And unlike the above 2 dialogs, this dialog is not modal i.e. one can click inside the applet area while this dialog is active

Steps to reproduce:
-------------------
1) Install any of the above mentioned bundles
2) Select JCP > Advanced > Denugging > Show applet lifecycle exceptions
3) Try running the following applets

4) Click Cancel on the security pop-up
5) "Application - error" dialog with "OK" and "Detail" button will be there
6)click on "Error : click for details" . With first applet one will see "Application - error" with "Details" and "Ignore" Button. And with second applet one will see "Application - error" with "Details", "Reload" and "Ignore" Button.
7)To test for modality ,against second applet try to click on "Error : click for details" while error dialog is shwoing up. If you are able to click and another error dialog shows up then modality issue is reproduced
