This is the FX counterpart of the [openjdk/jdk/pull/22131](https://github.com/openjdk/jdk/pull/22131) / `b.`(aka crash prevention part)
It does not crash without the [openjdk/jdk/pull/22131](https://github.com/openjdk/jdk/pull/22131) / `a.` part. The crash prevention part is the same for the JDK and JavaFX, except that this PR includes a test. ---- Internally the ScreenCast session keeps open for 2s (both JDK and JFX, and their implementations are almost identical). This is to reduce overhead in case of frequent consecutive screen captures. When we perform a [cleanup](https://github.com/openjdk/jdk/blob/db56266ad164b4ecae59451dc0a832097dbfbd8e/src/java.desktop/unix/native/libawt_xawt/awt/screencast_pipewire.c#L91) to close the session, we internally call [`pw_deinit`](https://docs.pipewire.org/group__pw__pipewire.html#gafa6045cd7391b467af4575c6752d6c4e). It becomes a problem if these sessions overlap in time, so that the second session cleanup crashes when it tries to call pipewire functions without initializing the pipewire system by [`pw_init`](https://docs.pipewire.org/group__pw__pipewire.html#ga06c879b2d800579f4724109054368d99) (please note that `This function can be called multiple times.`). So the solution is not to call `pw_deinit` because we don't really need it, and it needs to be applied to both the JDK and JavaFX. [jdk commit](https://github.com/openjdk/jdk/pull/22131/commits/19956fda202269e92ec70670bc88c8d3c7accf73) / [jfx commit](https://github.com/openjdk/jfx/pull/1639/commits/dba8a8871a38831d0a0da697a2be41f0c240c8f0) ---- The newly introduced test is disabled for now(as part of [JDK-8335470](https://bugs.openjdk.org/browse/JDK-8335470)), because it requires the fix on both the JavaFX and JDK sides. For the same reason `tests/system/src/test/java/test/robot/javafx/embed/swing/SwingNodeJDialogTest.java` and `tests/system/src/test/java/test/robot/javafx/scene/SRGBTest.java` are not enabled back. But if the JDK and JavaFX have the fixes, everything works fine. Testing in other different scenarios also looks good. ------------- Commit messages: - 8335469: [XWayland] crash when an AWT ScreenCast session overlaps with an FX ScreenCast session Changes: https://git.openjdk.org/jfx/pull/1639/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1639&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8335469 Stats: 156 lines in 3 files changed: 150 ins; 6 del; 0 mod Patch: https://git.openjdk.org/jfx/pull/1639.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1639/head:pull/1639 PR: https://git.openjdk.org/jfx/pull/1639
