<Swing Dev> [9] Review Request: 8076249: NPE in AccessBridge while editing JList model

[Mikhail Cherkasov]

Hello,

Could you please review the fix for jdk9?

AccessBridge works in separate thread,so if we modify JList model,
AccessBridge can request information about removed AccessibleJListChild or element
that changed position, so this can lead to NPE.
Almost all methods of AccessibleJListChild has checks for null, exception
those three where I added those checks.

Bug: https://bugs.openjdk.java.net/browse/JDK-8076249
Webrev: http://cr.openjdk.java.net/~mcherkas/8076249/9/webrev/

Thanks,
Mikhail.
