It should mostly revert JDK-8159048 (although the sentence added to
the class docs about animations running on the JavaFX app thread is
still valid), and some of the unit tests might still be valid.<br>

writing something up recommending that we do that. Phil and
I (and a couple others) had an offline discussion and think
this is the way to go.<br>

Given the short amount of time to get this into 22, I will
file the JBS issue in the next hour or so.<br>
<br>
Nir: if you want to take it, that would be great. Otherwise,
I will do it. We need the PR and CSR filed before the end of
this week.<br>
<br>
Regarding other methods that choose option 1, many of them
are more complicated (e.g., scene mutation can be done on a
background thread as long as the scene is not "showing") or
must be synchronous. Animation starts something that
conceptually happens later on the FX animation thread
anyway, so wrapping it in a runLater (if not already on the
right thread) doesn't really change the semantics in an
appreciable way.<br>

Thank you to Jurgen for raising the question and
to Nir, John, and Michael for evaluating it.<br>
<br>
I conclude that there is insufficient motivation
to revert the change in behavior implemented by
JDK-8159048 to allow calling the play/pause/stop
methods of Animation on a background thread.
Doing so without making it fully
multi-thread-safe would be asking for problems,
and making it fully multi-thread-safe would be a
fair bit of work to do it right without a clear
benefit.<br>
<br>
We will proceed with the current approach and
let JDK-8159048 stand. Further, we will proceed
with <a href="https://bugs.openjdk.org/browse/JDK-8324219" target="_blank" moz-do-not-send="true" class="moz-txt-link-freetext">https://bugs.openjdk.org/browse/JDK-8324219</a>

<div dir="auto">After playing around with the
code sample, I think that this is not the
right way to use the animation. The reason
is that there is no point in starting the
animation before the control is attached to
the scenegraph, or even made visible. A
small refactoring where, e.g., the
controller class exposes a method to start
the animation in onSucceeded or just calls
it on the FX thread is enough. I never start
an animation as part of the construction
because it's not the right time. John
suggested tying the lifecycle of the
animation to the showing of the node, which
also solves the problem.

PauseTransition or other non-interfering

<div dir="ltr">Hi Jurgen,
<div><br>
</div>
<div>What I'm confused about the
most is what it is you are
actually trying to do that
necessitates the use of animations
outside of the FX thread. You said
that you need to initialize
controls on another thread, and
that you are using Task (both of
which are fine), but how does
playing animations relate? Playing
an animation is something that is
done explicitly, usually in order
to manipulate data. Can you give a
real use case, like a minimized
version of what you're doing?</div>
