The approach from 1.6.0 has proven itself as unstable and multiple hard-to-understand bugs have been reported:
* JavaFx timer doesn't really work outside the main thread
* The frequent initialization pattern "runBlocking { doSomethingThatMayCallDelay() }" used on the main thread during startup now silently deadlocks
* The latter issue was reported both by Android and internal JB Compose users
* The provided workaround with system property completely switches off the desired behaviour that e.g. Compose may rely on, potentially introducing new sources of invalid behaviour
The original benefits does not outweigh these pitfalls, so the decision is to revert this changes in the minor release
Fixes #3113
Fixes #3106

BUG: Some jobs stay blocked forever in
delayfunction.I've been trying to figure out what the problem is. And it is because the delay is redirected to
kotlinx.coroutines.javafx.JavaFxDispatcher#schedule, where the delay is implemented as aTimeLinefor JavaFx. However, this Timeline is started outside of theJavaFX Threadand this will lead to unexpected results.Workarounds:
withContext(Dispatchers.Main) { delay(100) }- Dispatchers.Main is JavaFx thread in this case.kotlinx.coroutines.main.delay=false- switch off redirecting to JavaFxDispatcher (Dispatchers.Main)kotlinx-coroutines-javafxdependency (not possible for me)The text was updated successfully, but these errors were encountered:
