Java Swing JMenu's icon is not placed properly inside the menu

[shariq03]

I add only an icon to my JMenu.

If I use setPreferredSize(size of the icon) on JMenu, my icon is shifted to right in the JMenu.

If I use setSize(size of the icon) on JMenu, my icon is placed in center in the JMenu but has gaps on both sides.

Is there a way to align my icon properly or to expand so that its fills the menu space?

I can share my code snippets if required. Pic is attached.

Thanks
