Hello,
As the title says, I have errors with jAudioClip when compiling an exe with B4JPackager11 or Windows. I also tried with MediaPlayer, and get the same error when running the exe.

With MediaPlayer:
main._appstart (java line: -1)
java.lang.UnsupportedOperationException: Unsupported protocol "jrt"

With jAudioClip:

... 24 more

Both errors are related to "Unsupported protocol "jrt"". I couldn't find anything relevant on internet. My App runs fine in Release, Debug modes, or as a Jar, but the error happens when running the exe.

Thank you for your help.

EDIT: Solution: The Exe cannot access the audio or video files in File.DirAssets. Copy your files to File.DirApp or File.DirData.

Yes sorry, Java 11.0.1 (The one bundled on the download page of B4J)

Found this, maybe related
Yes that seems related, but no help from their side!

Ok Thanks, that lead to the answer I guess:
https://bugs.openjdk.java.net/browse/JDK-8209180

CUSTOMER SUBMITTED WORKAROUND :
The work around is to leave the media file outside of the custom image and load it using a file: an http: or an https: URL. But that goes counter to the purpose of building a custom image.

We cannot load from File.Dirassets
