Freezing when launching external viewer on Linux

[Dansoftowner]

Hi @stephansann ,

I tried Document Archiver on my Ubuntu machine. I experienced that the app freezes when I try to open the external editor for the particular file.

The funny thing is that no exception occurs.

Fortunately, I had the same problem with the java.awt.Desktop API in my application on Linux systems and now I know what is the solution. So basically you should execute the Desktop.getDesktop().open(...) command on an another thread. I used an ExecutorService:

ExecutorService executor = Executors.newCachedThreadPool(); // just an example
executor.submit(() -> Desktop.getDesktop().open(file));

Hope you find this report useful! Best regards Daniel

Hi @Dansoftowner

Thanks a lot for the report.

Could you maybe share the file this is happening with?

Anyhow I will have a look at the code and change it as suggested.

Best regards Stephan

It happens with every file I tried, the problem is not with the files. It's basically a bug on linux, but somehow invoking the Desktop API method on another thread solves the problem.

Thanks Stephan
