Huh, I found another issue.

test/jdk/java/awt/MenuItem/LotsOfMenuItemsTest.java line 107:

The original test had `setVisible(true);` here. This is why the loop contains `setVisible(false)`.

Without showing the frames, the test may not reproduce the original problem reported in [JDK-4175790](https://bugs.openjdk.org/browse/JDK-4175790).
