我在我的 .bashrc 文件中设置了这样的 JAVA_HOME:

I have JAVA_HOME set like this in my .bashrc file:

JAVA_HOME=/usr/lib/jvm/default-java  #Which is a symbolic link to java-7-openjdk-common
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH

java -version 的输出是:

java version "1.6.0_23"
OpenJDK Runtime Environment (IcedTea6 1.11pre) (6b23~pre11-0ubuntu1.11.10.2)
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

javac -version 的输出是:

javac 1.7.0_147

我的问题是，为什么 com.sun.tools.javac.util.List 不包含在类路径中?

My question is, why com.sun.tools.javac.util.List isn't included in the classpath?

推荐答案

这个类位于 tools.jar 中，它不是 JRE 的一部分.

This class is found in tools.jar, which is not part of the JRE.
