Java Error in Loading Additional Pages on Large Table when JAB is enabled

When working with large table, java loads additional page of data
unneeded and causes the application to freeze.

When table navigation goes directly to the last row of data
through <Shift TAB> key, the last page of data is loaded
correctly.

At the moment, <ALT> key is pressed to navigate the menu item
on top, java loads all the pages of data unneeded.
The unnecessary loading causes the application to pause.
User should be able to navigate the menu item without
delay any time when the application is running.

Additional pages of data should not be loaded at this
time as they are not requested through table navigation.
