Hi Andrew,
1) There is no memory leak in this program. My user just tries to load
too many information from the database and it is not easy to estimate
the memory required to store and to show data on the screen. I usually
show a message "This query may be too long ..." to my user before
retrieving data, but it is up to he/she to start an execution. This is
the reason why I have this problem.
2) I already created an invisible error message box and I am going to
make it visible if error detected.
Regards,
Serguei.

Dear Experts,
My GUI application sometimes runs out of memory with the message like
the following:
Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java
heap space
I try to catch this exception with:
1) The Thread.UncaughtExceptionHandler
2) try / catch block "around" my main class
but both attempts do not work.
Is there a simple way to catch exceptions in AWT thread?
An exception in another thread is harder to catch .
But that is not an Exception, it is an Error, what are you 'catch'ing?
Sun distinguishes between them because errors are more serious.
In fact, your options are very few if you do manage to catch it.
After all, there is no more memory to instatiate new objects
(such as a warning dialog).
Also, it is important to track down the cause of this error
and fix it, as the program probably has a memory leak.
