Eclipse (C/C++) - Fehler: Der Job wurde nach dem Herunterfahren der Plattform noch ausgeführt

Beim Öffnen von Eclipse, das vor einer Stunde funktioniert hatte, erstarrte es beim Starten und gab den Fehler: "Ein Fehler ist aufgetreten. Sehen Sie sich die Protokolldatei an." Siehe die Protokolldatei unten.

Obwohl einige dieser Informationen im Protokoll angezeigt werden,

Betriebssystem: Mac OSX 10.7.5

Eclipse: Eclipse IDE für C/C++ - Entwickler 3.8

Außerdem habe ich versucht, die ausführbare Eclipse-Datei mit -clean zu starten und verschiedene Dateien im Ordner .metadata zu löschen. Viele Lösungen im Internet, bisher hat keine funktioniert.
