Looks like there was a little delay in processing it, so I moved it to
the JDK project myself. It is available here:
https://bugs.openjdk.org/browse/JDK-8293971
I've also added the additional information you sent below to the bug report.

In the in between time I found that this line in the JFX source is
responsible for the bug:

primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();

Media(getClass().getResource("/static.mp3").toURI().toString()));
player1.setAutoPlay(true);

Hello all,
After this commit:
https://github.com/openjdk/jfx/commit/d1110f479567c314ecb6848700bcf4552509d7e9
<https://urldefense.com/v3/__https://github.com/openjdk/jfx/commit/d1110f479567c314ecb6848700bcf4552509d7e9__;!!ACWV5N9M2RV99hQ!OeWMVVpaLY2NEWr0uLfT_Z4m_fQyPCpg1VoPzXGJVl4B5NYW5UHkW4FF1w7Q22gqI2nX6OWhogndXvvg6gsuYwdhZtzPsZM$>
Creating a new Media object using a MP3 file in the resources
of a project, you can get exceptions:
Exception in thread "JavaFX Application Thread"
MediaException: MEDIA_UNSUPPORTED : Unrecognized file signature!
at
javafx.media@20-ea/javafx.scene.media.Media.<init>(Media.java:411)
At first glance, the error is in this Locator file in the
JavaFX source code:
https://github.com/openjdk/jfx/blob/master/modules/javafx.media/src/main/java/com/sun/media/jfxmedia/locator/Locator.java
<https://urldefense.com/v3/__https://github.com/openjdk/jfx/blob/master/modules/javafx.media/src/main/java/com/sun/media/jfxmedia/locator/Locator.java__;!!ACWV5N9M2RV99hQ!OeWMVVpaLY2NEWr0uLfT_Z4m_fQyPCpg1VoPzXGJVl4B5NYW5UHkW4FF1w7Q22gqI2nX6OWhogndXvvg6gsuYwdhb7Gu6w0$>
*Steps to reproduce the bug:*
1. Create a new Media object and load an MP3 from the resources
2. Watch the Media object throw a MediaException:
MEDIA_UNSUPPORTED : Unrecognized file signature!
*Example code that produces the bug:*
final MediaPlayer mediaPlayer = new MediaPlayer(new
Media(getClass().getResource("/path/to/file.mp3").toExternalForm()));
*Extra:*
I've made a free MP3 file available to try with here (royalty
free):
https://codedead.com/static.mp3
<https://urldefense.com/v3/__https://codedead.com/static.mp3__;!!ACWV5N9M2RV99hQ!OeWMVVpaLY2NEWr0uLfT_Z4m_fQyPCpg1VoPzXGJVl4B5NYW5UHkW4FF1w7Q22gqI2nX6OWhogndXvvg6gsuYwdhb65LOH4$>
I've also got a GIT repository in which the exception occurs
immediately when running the Gradle task 'application':
https://github.com/CodeDead/opal/tree/development
<https://urldefense.com/v3/__https://github.com/CodeDead/opal/tree/development__;!!ACWV5N9M2RV99hQ!OeWMVVpaLY2NEWr0uLfT_Z4m_fQyPCpg1VoPzXGJVl4B5NYW5UHkW4FF1w7Q22gqI2nX6OWhogndXvvg6gsuYwdha9sC5sE$>
(please make sure to use the development branch as this
branch makes use of the latest JavaFX versions)
Oddly enough, it does not always happen, and loading the file
directly from a file location instead of the project
resources seems to work, but when loading from the resources,
you get the exception that the media file signature is not
recognized.
I don't see a problem with the media files themselves,
encoding is all fine, at first glance and because it worked
in JavaFX 18.0.2, creating a Media object using a URI to a
project resources location should work in newer versions as
well, I think. The same MP3 file does work when you load it
from the disk instead of the project resources so this makes
it a bug, I believe.
The work-around right now is to revert back to JavaFX version
18.0.2.
*System / OS / Runtime info:*
