JasperReports, NoClassDefFoundError: org/apache/commons/javaflow/bytecode/Continuable

Neulich habe ich mir JasperReports 2.0.4 und iReport 2.0.4 runtergeladen. Ich habe mir mit iReport einen Report zusammengeklickt und aus iReport heraus den Report compiliert. Nachdem ich die compilierte Datei in mein Eclipse-Projekt kopiert habe und diese in meinem Programm verwenden wollte, erhielt ich die folgende Exception.

Der Fehler kann sehr leicht behoben werden. iReport 2.0.4 benutzt die Bibliothek commons-javaflow-20060411.jar. Nachdem ich diese Jar-File zu meinen Bibliotheken hinzugefuegt habe, trat der Fehler nicht mehr auf.
