Java Swing window not showing

I have uploaded 2 .java files one is

ShapedWindow

ShapedWindow

and second

Window

Window

. When running

ShapedWindow

ShapedWindow

the window appears as expected and UI works.

ShapedWindow

ShapedWindow

is basically few copypasted snippets together, so I wanted to rewrite it with Anonymous class overriding JPanel as seen in

Window

Window

class but when running that, GUI does not show up, as if the call to display does not happen. Since biggest change was the Anonymous class I would be looking for issue there but I am not sure what exactly I am looking for.

Is there a way of doing this better?
