RFR: 8339233: Test javax/swing/JButton/SwingButtonResizeTestWithOpenGL.java#id failed: Button renderings are different after window resize

[Manukumar V S]

This is a highly intermittent failure, it failed only once in CI on a particular windows machine and passed on all other runs. 

Failure reason:
When the button was displayed for the first time, the focus rectangle drawn on the button text(Button A) was not seen(failure images attached in the bug).

Fix:
To stabilize the test, I have added a line -> button.setFocusPainted(false), so that the focus rectangle will not be painted
