文件名是bluej-205.jar
执行:java -jar bluej-205.jar
显示如下:
libgcj-java-placeholder.sh

This script is a placeholder for the /usr/bin/jav
a
master link required by jpackage.org conventions.
  libgcj's
rmiregistry, rmic and jar tools are now slave sym
links to these
masters, and are managed by the alternatives(8) s
ystem.

This change was necessary because the rmiregistry
, rmic and jar tools
installed by previous versions of libgcj conflict
ed with symlinks
installed by jpackage.org JVM packages.
