Ich benutze Eclipse Oxygen mit WindowBuilder Pro unter Debian Buster und wenn ich eine .java Datei (mit einem Swing JFrame) im Design Tab öffnen möchte, Ich bekomme einen "Designer, No more handles" -Error. Danach werde ich gefragt, ob ich die Workbench verlassen möchte, weil mehr SWT-Fehler auftreten könnten und es könnte unerwartet geschlossen werden.Wie löst man "No handles exception", Eclipse Oxygen, Windowbuilder Pro
Nachdem ich auf "Nein" geklickt habe, sehe ich immer noch den Designer, reagiert jedoch nicht auf Klicks oder Bewegungen, die versuchen, den JFrame zu ändern.
Fehler Stacktrace:
