These changes are intended to stabilize testing on Wayland in X11 compatibility mode.
<hr> Many tests may fail if there is no `robot.delay()` call after `robot.waitForIdle()` (right after displaying a window). <hr> Some tests do not release previously pressed mouse button/key, this leads to other test failures later, but it is not a problem for X11 session. I haven't checked this, but it looks like the XWayland server does not release the key/button emulated by XTEST when the client application disconnects, while the regular X11 server does. <hr> For some tests it is critical to call AWT code on EDT(it prevents NPE): java/awt/List/KeyEventsTest/KeyEventsTest.java java/awt/Paint/ListRepaint.java <hr> Some other explanations can be found inline in the comments for a specific test. <hr> Testing is green on all platforms. ------------- Commit messages: - 8327401: Some jtreg tests fail on Wayland without any tracking bug Changes: https://git.openjdk.org/jdk/pull/19339/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19339&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8327401 Stats: 736 lines in 24 files changed: 300 ins; 213 del; 223 mod Patch: https://git.openjdk.org/jdk/pull/19339.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19339/head:pull/19339 PR: https://git.openjdk.org/jdk/pull/19339
