This PR removes all `StubToolkit` checks from JavaFX production code. There are only a few.
Two notes: Note 1: `TableRowSkinBase`s `DO_ANIMATIONS` is now `true` for tests. It was not before due to a leak (as far as I could find when digging). But I could not find any problem, even running all tests with `-Xmx512m` Checking tests that trigger the affected code path and creating a heapdump after, I could not see anything weird: > Heapdump after `TreeTableViewResizeTest`: <img width="859" height="542" alt="image" src="https://github.com/user-attachments/assets/744d27f2-73e7-4213-ae6f-63b0c2b10f7a"; /> <img width="858" height="347" alt="image" src="https://github.com/user-attachments/assets/0a873611-ae76-4ea9-82b6-bad4cba84fd3"; /> Note 2: Now when the tests run in CI, `JavaFX: using test.com.sun.javafx.pgstub.StubToolkit` is now printed 12 times (probably the amount of Unit Test Threads): <img width="1451" height="514" alt="image" src="https://github.com/user-attachments/assets/c0a9f49d-5d37-4df6-a15a-4aa4cb1b4b83"; /> If this is a problem, we can decide if we want to change the print code in `Toolkit` (in a follow-up). --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8382049: [TestBug] Multiple StubToolkit checks in JavaFX production code Changes: https://git.openjdk.org/jfx/pull/2146/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=2146&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8382049 Stats: 69 lines in 6 files changed: 18 ins; 31 del; 20 mod Patch: https://git.openjdk.org/jfx/pull/2146.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/2146/head:pull/2146 PR: https://git.openjdk.org/jfx/pull/2146
