在折腾：
【记录】尝试使用ANTLRWorks 2.0去进行ANTLR开发
的过程中，用ANTLRWorks 2.0编译运行Hello.g4，结果出现警告和错误：
全部log为：

【解决过程】
1.很明显，看起来像是，不支持JAVA7，希望的版本是JAVA6。
2.所以去：
卸载当前的JDK7
3.去
http://www.oracle.com/technetwork/java/javase/archive-139210.html
下载到：
重新安装JDK 6。
4.然后再次运行，此警告就消失了。
【总结】
貌似ANTLRWorks 2.0，不支持JDK 7？
不过后来的结果证实，貌似JDK 7，好像没有对antlrworks产生本质的影响，即
不论是jdk6还是jdk7，其实都不影响antlrworks的使用的。
接下来，就是去解决对应的error了：
