probably unnecessary but some of these fields might be used on different threads, so just in case.

The test should wait until the frame will be disposed.
"invokeLater" was added [here](https://github.com/openjdk/jdk/pull/19339/files#diff-6141b9cfb077259bad37ff9fd15782c5bb31d9c52aadc81a177d9057e177d415R55),

The test was changed [here](https://github.com/openjdk/jdk/pull/19339/files#diff-054074499ab6611e764a315fb13c51af4ad063b07f481e775a2262196077d285R69), the root cause of the failure discussed in https://github.com/openjdk/jdk/pull/19339/files#r1609189736 is a product bug: https://bugs.openjdk.org/browse/JDK-8201307.

The purpose of the test is to run some methods of the AWT component on the main thread and check if it will be refreshed on the EDT. It was changed [here](https://github.com/openjdk/jdk/pull/19339/files#r1609190355). It is a product bug: https://bugs.openjdk.org/browse/JDK-8201307.

test/jdk/javax/swing/JButton/bug4490179.java line 85:

> 83:             robot.mousePress(InputEvent.BUTTON3_DOWN_MASK);
> 84:             robot.mouseRelease(InputEvent.BUTTON3_DOWN_MASK);
> 85:             robot.delay(3000);

The test was discussed [here](https://github.com/openjdk/jdk/pull/19339/files#r1609201116). It seems that the purpose of the test is to check that no events will be generated while the left button is pressed, so we should check that "ActionListener" is not triggered and then release the mouse button.
Thoughts?
