Issue : VO doesn't announce Tab items of a JTabbedPane as RadioButton which is wrong.
Analysis : That is due to the role mapping of tab items as `NSAccessibilityRadioButtonRole` in `JavaAccessibilityUtilities.m` file. Since the accessibility role description is fetched in `accessibilityRoleDescription` API if `CommonComponentAccessiblity.m` file, the sub-role passed as a parameter is `nil`, returned value is RadioButton.. Proposed Fix : Fix is to get the correct accessibility role description from Appkit, we should pass `NSAccessibilityTabButtonSubrole` in the subrole parameter and that returns the accessibility role as `Tab` and is announced correctly by VO. ------------- Commit messages: - Tab item announcement fix Changes: https://git.openjdk.org/jdk/pull/26096/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=26096&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8361283 Stats: 8 lines in 1 file changed: 6 ins; 0 del; 2 mod Patch: https://git.openjdk.org/jdk/pull/26096.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/26096/head:pull/26096 PR: https://git.openjdk.org/jdk/pull/26096
