UML용 Visual Paradigm을 설치하면 다음이 발생합니다. java.lang.NoClassDefFoundError: java.awt.Container

Question

최근에 UML용 Visual Paradigm을 내 시스템(Ubuntu 12.0.4 LTS)에 다운로드했습니다.

설치하려고 했더니 실패했어요. 스택 추적은 다음과 같습니다.

설치 프로그램이 WT 라이브러리에서 클래스를 찾을 수 없는 것 같습니다. 어떻게 그게 가능한지 모르겠습니다. 이 문제의 원인이 무엇인지, 어떻게 해결할 수 있는지 아는 사람이 있나요?
