libgcj-java-placeholder.sh

This script is a placeholder for the /usr/bin/java

master link required by jpackage.org conventions. libgcj's

rmiregistry, rmic and jar tools are now slave symlinks to these

masters, and are managed by the alternatives(8) system.

This change was necessary because the rmiregistry, rmic and jar tools

installed by previous versions of libgcj conflicted with symlinks

installed by jpackage.org JVM packages.

This script was designed to be overridden by the supported RHEL3 JRE

packages, java-1.4.2-bea and java-1.4.2-ibm. It is installed as an

alternative symlink as /usr/bin/java. It will override a third-party

(non-RHEL3) JRE's java command if the JRE's bin directory is listed

after /usr/bin in PATH. In that case, it is recommended that the

third-party JRE's bin directory be listed first in PATH instead.

你用的是linux吧：

/usr/bin/java 这个命令是一个软连接，其连接到libgcj-java-placeholder.sh这个脚本。运行/usr/bin/java等于运行libgcj-java-placeholder.sh

上面显示的是运行libgcj-java-placeholder.sh打印出来的信息。是关于这个脚本的说明。

java -version是java命令的带参数执行，查看当前java版本，是由path决定，dos下，window按照path的路径寻找可执行命令。
