今天在SL下build JRex，在执行ant make的时候总是出现以下错误：

compile: [javac] Compiling 86 source files to /Users/ijay/Projects/mozilla/embedding/JRex/classes [javac] /Users/ijay/Projects/mozilla/embedding/JRex/src/java/netscape/javascript/JSObject.java:38: ?????? sun.plugin.javascript ??????

检查了一下build.xml引入的JRex.properties，其中有一行内容如下：

classpath =${build};${java.home}/lib/plugin.jar;${java.home}/lib/deploy.jar;${java.home}/lib/jaws.jar

于是又挨个去找那几个jar包（其中“plugin.jar”最像），最终发现了问题：/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/plugin.jar（即“${java.home}/lib/plugin.jar”）是一个符号链接，指向“/System/Library/Frameworks/JavaVM.framework/Versions/A/Resources/Deploy.bundle/Contents/Home/lib/plugin2.jar”，而plugin2.jar不存在…… 把原先的符号链接删除，重建链接指向…/plugin.jar，问题解决 已向apple提交该bug
