crash when opening rainbow (Linux)

[Former user]

Hi, I downloaded and unzipped the current Okapi app package for Linux x64, but when I run rainbow.sh, I only get a dialog box („Error“/„The error is null“). Here’s the terminal output:

Picked up _JAVA_OPTIONS: -Dswing.crossplatformlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel

Hello! Thanks for this report. What version of Okapi was this? (The mostly likely versions are the latest release, 0.29, or the latest snapshot, 0.30-SNAPSHOT.)

Even adding the "-Dswing.crossplatformlaf=com.sun.java.swing.plaf.gtk.GTKLookAndFeel" option I don't get a crash with M30 or M29 on my Ubuntu 14.04. They might want to try to add theses options to the rainbow shell script:

export SWT_GTK3=0 export LIBOVERLAY_SCROLLBAR=0 export GDK_NATIVE_WINDOWS=true

We have not been able to replicate the crash. And since this is more than a year old, we can close it.
