RE: Selenium Unexpected modal dialog popup exception

I am running my application,and “modal dialog ┬ápopup” exception occurs randomly and terminates the application.
I have handled the exception in code by catch,& finally block  but it fails to handle.

Exception snippet:-
org.openqa.selenium.UnhandledAlertException: Unexpected modal dialog (text: Active Data Service DataUpdateManager is NULL): Active Data Service DataUpdateManager is NULL
