#1206 Application freezes after closing preferences window

[J. Dumas]

Hi everyone.

I have witnessed an odd behavior with Jabref and I would like some help to diagnose it (I would like to know if there is a problem with my config of if this is a Jabref bug).

What happens is that when I open the Options > Preferences windows, and then close it, the application doesn't respond anymore and has frozen (as if it didn't really close the pref. window). It happens whether I do any action in the pref. window or not, no matter if I click on "Ok" or "Cancel".

It happens with the last stable version (2.9.2) as well as the beta (2.10b). I'm running an up to date Arch Linux with java version 1.7.0_51 (OpenJDK), and my window manager is i3 (see http://i3wm.org/).

i3 is a re-parenting window manager so the following workaround isn't really helpful in my case:

export _JAVA_AWT_WM_NONREPARENTING=1

I have set the options:

export _JAVA_OPTIONS='-Dawt.useSystemAAFontSettings=on -Dswing.aatext=true -Dswing.defaultlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel'

But then again, the problem also appears when no option is set and the default metal theme is used.

Could someone help me identify where the problem comes from and how to solve it?
