Hallo,

um die Fehler einzuschränken empfehle ich das hinzufügen der Befehlszeile:
JAVA_OPTS=”-Djava.awt.headless=true -XX:+UseConcMarkSweepGC -Xms386M -Xmx2048M -XX:MaxPermSize=386M”

da das environment die Änderungen anscheinend bei manchen Systemen nach einem Neustart des Systems nicht zieht empfehle ich weiterhin, dass entfernen der Zeile aus dem /etc/environment und das Eintragen in das Programm Tomcat, bei Standard Installationen ist das /etc/default/tomcat7

Beste Grüße
