hangs if opening one of several files

[JoKalliauer]

JabRef version JabRef 5.0-beta.382--2020-01-28--0b53d4b on Ubuntu 18.04

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Steps to reproduce the behavior:

1. Open watson.bib.txt in JabRef on Linux (can't reproduce on Windows)
2. click on the file-button of the entry
3. choose the second one
4. File opens (The file must exist, otherwise the problem does not occur)
5. Mouse moves, but clicking does not do anything and keyboard also does not interact, but computer sill runs e.g. Systemmonitor does still update graphics, but does not interact with input (all programms cummulated: 30% RAM-usage, ~5%CPU usage)
6. ssh to my PC, and kill JabRef
7. everything works again, JabRef gone. (25% RAM-usage, ~5%CPU usage)

Symptoms sound like #5919 , except I don't understand the connection with this specific file.

JabRef 5.0-beta.407--2020-02-06--9407bef
Linux 4.15.0-87-generic amd64
Java 13.0.2

I just checked and "alt" "F4" works (pressing twize once for the LibreOffice/PDF-viewer and second for Jabref) and Print also works, but "Windows-Key"/"apple-Key"/"super-key" (don't know the name) did not work.

The error exists also with sudo swapoff -a (at least with the older version JabRef 5.0-beta.382--2020-01-28--0b53d4b )

Linux 5.3.0-28-generic amd64
Java 13.0.2

I can confirm this issue for Linux. As far as I can tell, the problem arises when someone tries to open a file. It does not matter, what type of file - I have tried to use a different PDF and even a .txt file instead and it would still crash the application (though with the .txt file it might be necessary to use the context menu for the file (Right click -> Open) to trigger the crash).

In three cases, an error log file was generated. I am not sure, whether these error log files relate to the actual issue or whether they just show, that I had to shut down the whole system to get it back working, but in case they are useful, here they are:

[Siedlerchr]

I just merged a fix regarding opening files. Should be fixed now in master.
Please wait some time until the new master is uploaded.-

Linux 5.3.0-40-generic amd64
Java 13.0.2

Cannot confirm for the current master version. If I right-click on a file, the context menu will open. If I then press "Open" to open the file, the application that opens the file will hang and has to be forcefully shut down.
Note, that this issue does not appear any more if the file is opened with a simple left-click. As far as I can tell, this problem only arises now, if right-click and the associated context menu are used to open a file.

[Siedlerchr]

Okay, thanks for the update. Will look into it. Might be that the context Menu calls another method which I oversaw.

On my PC the example above seems to be solved/fixed. @Siedlerchr : Thanks

I consider the issues as solved (on my Ubuntu) and could be closed.

open file (F4) works for me on Fedora Linux.

In my reading, this issue can be closed.

Hmmm, it does not crash for me anymore, but there are other issues:

1. Every time I try to open a PDF, a new window "Open with" opens, which asks me which application should be used to open the PDF. Given that the default PDF reader should be set in Ubuntu (if I doubleclick a PDF in the file manager, it will automatically open, without asking me which application to use), this appears to be an undesired behaviour. Could it be linked to some sort of interaction between Snap and then Gnome Filemanager?

2. F4 does not work for me, i. e. no file is being opened if I press F4. A leftclick, however, allows me to open a PDF (well, if first shows the windows mentioned in 1) and after I select the application it opens the PDF).
