This test depends on the next windows UI performance option: “Show window contents while dragging”, see https://answers.microsoft.com/en-us/windows/forum/all/in-windows-7-how-do-i-show-window-contents-while/18e3aee2-bcc7-4005-a45d-c5613cf6eb3c
In the default configuration, the windows may decide that the system is slow and this option should be disabled. I have found that this usually happens in the virtual environment. When that option is disabled the resize events have come when the user completes the resize, before that the only border "rectangle" is moved. This fix changes the test to release the mouse and complete the resize, and only after that checks the result. Also, some old machinery is removed. ------------- Commit messages: - Update AncestorResized.java Changes: https://git.openjdk.java.net/jdk/pull/5711/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5711&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8225122 Stats: 206 lines in 1 file changed: 5 ins; 178 del; 23 mod Patch: https://git.openjdk.java.net/jdk/pull/5711.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5711/head:pull/5711 PR: https://git.openjdk.java.net/jdk/pull/5711
