Hi all,
I'm experiencing something very strange with my JavaFX clojure
application. What the application actually is about is not super
important. What is important is the fact that I'm having a different
experience when I run it via `lein run` (or in fact `lein trampoline
run`), than when I run the created uberjar (via `lein uberjar`).
The difference is the following:
In my `-start` method I'm creating a MediaPlayer object (with a .wav
resource), and setting its cycleCount to INDEFINITE, which is to say
that is will keep repeating the audio file forever. That's all fine and
dandy and it does work as expected when run through lein. However, the
exact same code in the uberjar plays the file once and then it stops!
The game carries on as usual with no exceptions or anything like
that...It's only the music that stops!
Now, before someone says that the MediaPlayer object has been GC'ed (as
indicated by [1], [2] & [3]), I should point out that I am able to
restart the music (by pressing 'M)' after it has stopped and while the
program is running normally. The only thing that the KeyCode handler for
M is doing calling `.play` or `.stop` on the original MediaPlayer object
i created at the very start. In other words, I'm not creating any new
MediaPlayer objects anywhere else other than the `-start` method. Unless
I'm missing something, i shouldn't be able to restart the music if the
MediaPlayer object had been GC'ed, right?
I'm not sure if it plays any role but the MediaPlayer object lives
inside a promise, which again is delivered in the `-start` method, right
before the javaFX Scene is shown. So the controls that need access to
that MediaPlayer object (like the <M> handler mentioned earlier), go
through that promise to get it. I only did that because i want to have
it as a global in that ns, but at the same time i can't just `def` it
because the javaFX toolkit is not initialised at compile time. So it's
either going to be a `promise` or a `delay`. In any case, I'm really not
sure how/why this would be an issue - I'm just throwing it out there as
an 'interesting' complication in case I'm wrong.
Other than that, everything seems to work as expected, which is the same
as with `lein run`. Feel free to drop suggestions, and/or brainstorm
ideas. I could even provide the project in a zip if you would like to
experience it yourself.
Thanks in advance...
Kind regards,
Dimitris

Mine stops after the first cycle every time (which is between 15-16 seconds)
