[jdk11u-dev] RFR: 8339728: [Accessibility,Windows,JAWS] Bug in the getKeyChar method of the AccessBridge class

[Antonio Vieiro]

Backport of [JDK-8339728](https://bugs.openjdk.org/browse/JDK-8339728) from 17u that solves some accessibility issues on Windows, for parity with 11.0.27/28-oracle  (and because it's marked as CPU25-critical-SQE-OK too). Low risk.

The test does fail without this fix (when read-out, the short-cuts are truncated, so for instance the menu short-cut "Ctrl+Shift+Period" was read out as "Control plus Shift plus P", instead of "Control plus Shift plus Period".

The new accessibility test passes on Windows 10 (tested with [JAWS v. 2025.2412.102 - February 2025](https://support.freedomscientific.com/Downloads/JAWS) ).

Clean but for an update in copyright header and for a multi-line string (that has been replaced) in `AccessBridge.java`.
