Test fails in macos27 suggesting the drag didn't happen properly..Test was supposed to drag 1st column header "A" to last column header "E" and expects the final output to be "A" after drag completion but it gets `java.lang.RuntimeException: Unexpected header's value; index = 4 value = E`
It seems to be a macos issue as seen in [JDK-8322653](https://bugs.openjdk.org/browse/JDK-8322653) whereby mouse clicks are not received within 3 pixels of windows boundary and test uses `robot.mouseMove(point.x + 3, point.y + 3)` Fix is made to start the drag operation from center of 1st header cell till center of last header cell --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8396623: [macos27] javax/swing/JTableHeader/6884066/bug6884066.java test fails Changes: https://git.openjdk.org/jdk/pull/33738/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=33738&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8396623 Stats: 13 lines in 1 file changed: 7 ins; 0 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/33738.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/33738/head:pull/33738 PR: https://git.openjdk.org/jdk/pull/33738
