Java APIs

I'm trying to create a method/function to determine if my app can create offscreen images using awt, and thanks to suggestions here in this forum I've been pointed in the direction of headless mode/state.

From what I've gathered: If an unsupported operation is attempted, a HeadlessException is thrown.
Therefore I hoped this would do the trick:

public boolean canDraw()
{
    boolean rv = true;

    try
    {
         Color c = new Color(100,100,100);
    }
    catch (HeadlessException he)
    {
          rv = false;
    }
    
    return rv;
}

But, alas, no HeadlessException is caught, and the app crashes.
Where am I thinking wrong?

Grateful for any help,
