Opening the File Chooser on Linux instantly crashes the player

[xeruf]

It opens a blank file chooser window and then instantly crashes. The issue seems to lie in JNA.

How did you come to the conclusion that JNA is related to this?

I'd like for you to make a very simple JavaFX application/demo that opens a standard JavaFX File dialog and see it the problem persists. The file chooser should just work.

Please see this:

A directory chooser I tested worked without issue, but I will investigate further.
This screenshot shows how it looks for literally a splitsecond before the crash:

Thx for the report. This could be related to extension filters (audio) passed into the chooser.

I will try setting up a Linux VM to reproduce and fix the issue.

This may be a bug on your side. I'm running VM with Linux Mint using Vmware on Windows and I am able to open both directory and file chooser.

I'm running

• (latest official) Linux Mint 18.3 Sylvia
• on OracleJDK 9.0.4+11
• I launched the application manually (no IDE, no script) from working directory with command like ./jre/bin/java -cp '.:PlayerFX:lib/*" sp.it.pl.main.AppUtil (I havent included the add opens arguments here...)

Because I can not reproduce this I can not test workarounds.

One possible cause I can imagine is the extension filter. Please see Environment.class and chooseFile/chooseFiles methods and remove the line setting the extensions: this.extensionFilters += extensions.

[xeruf]

wait how does the application work without the add-opens?

I'll test your suggestion when I get back to my PC

[sghpjuikit]

I havent included the add-opens here for brevity. I have included it in the launch command.

[xeruf]

nope, removing the extensionfilters still didn't work

[sghpjuikit]

This may be a threading issue (Javafx vs Swing), one of the FileChooser parameters, JDK bug or OS bug. I will continue to try to reproduce the behavior, but until then you can try to eliminate possibilities. For example, what happens if you open some FileChooser in the App.init() or App.start() method? And so on.

at least I can drag in songs as a workaround ^^
