Das liest sich nach einem AWT Bug an. Da die ganze Java VM weg ist, kann ich da gar nicht mehr eingreifen.

Ich sehe Du verwendest OpenJDK 1.8.0_172-b11. Das ist ziemlich neu.

Es gibt ähnliche Reports. Dieser Eclipse Bug deutete daraufhin, dass es daran liegt, dass AWT GTK2 nutzt, aber PP jetzt per Default auf GTK3 setzt. Und beides zusammen Probleme bereitet. Mir ist nicht ganz klar wie ich das auflösen kann da ich AWT an einer Stelle nutzt: um den externen Browser zu öffnen (und das platform-übergreifend).

Hier der relevante Text:

Awt loads GTK2. and eclipse by default starts in GTK3. GTK2 and GTK3 cannot be loaded in the same process. That is the reason you are seeing this crash.

the workaround is to use GTK2 for eclipse as well. This can be achieved in the following ways

add the following lines to eclipse.ini before -vmargs(recommended approach)
–launcher.GTK_version
2

set the environment variable SWT_GTK3 to 0 before launching eclipse. you need to do this every time you launch eclipse

Statt “eclipse.ini” müsstest Du “PortfolioPerformance.ini” editieren.

Das scheint ein Problem von webkitgtk gewesen zu sein, seit Update auf Version 2.20.3 gibt es keine Abstürze mehr.

Hallo Andreas,

habe mal in der portfolio.ini

auf GTK 2 umgestellt.

Damit kann ich die Browserlinks aufrufen.

Leider funktionieren dann die Grafiken in Bestände, Donuts etc nicht mehr.

Wenn ich jdk austauschen würde, wie hier

https://wiki.archlinux.org/index.php/java#GTK3_Support

klappt es vielleicht.

Habe jetzt openjdk 9 installiert ,

damit kann ich wider alle Browserlinks aufrufen

und die Grafiken mit gtk 3 funktionieren auch.

Vielen Dank für den Link. Ich nehme das Argument mit auf damit der nächste nicht in die gleichen Problem läuft.
