<Swing Dev> RfR JDK-8145207 [macosx] JList, VO can't access non-visible list items

[Anton Tarasov]

Hi Pete,

I went through the fix and found it looking fine to me, except for these two minor issues:

- JavaComponentAccessibility.m

In this chunk:

+- (void)postSelectionChanged
+{
+    NSAccessibilityPostNotification(self, NSAccessibilitySelectedChildrenChangedNotification);
+}

AWT_ASSERT_APPKIT_THREAD is missing.

- CAccessibility.java

A typo in the comment: "will will annouce” 

Also, I gave it a try with jdk8u-dev, locally, along with the following pre-applied:

8076554: [macosx] Custom Swing text components need to allow standard accessibility

JList is spoken fine by VO, though I wasn’t able to make the following:

VO+up/down just moves up/down the sibling panels (conforming https://www.apple.com/voiceover/info/guide/_1131.html <https://www.apple.com/voiceover/info/guide/_1131.html>) but not the list items.
Could you please shed a light on it?

Thanks,
Anton.

P.S.
Will it be possible to back-port it to 8u-dev?
