Problem in JTable row selection

Dear Friends,
I'm using JTable in my application. It has 4 columns and rows are fetched from database. 1st column contains JCheckBox to select the particular row in the table. 1st column header also contains JCheckBox. All rows in the table are selected and unselected by check and uncheck the column header JCheckBox.

The problem is,
If I check anyone of the row JCheckBox then the particular row got selected and If I check the column header JCheckBox then that check box is checked and all rows are selected.

But If I check the 1st row JCheckBox then the 1st row got selected and If I check the Column header JCheckBox then column header JCheckBox is chekced but no rows are selected (1st row also deselected).

I tested the same scenario for 2nd and 3rd rows but everything works fine. Only 1st row gives this problem.

My Code is,

APUCheckBoxHeader class :

MyItemListener class :

Could anyone please tell me how to solve this issue?

Thanks in advance,
