Install4j Mac OS X 安装程序抛出 NullPointerException

Question

查看 installation.log 我发现我的 Mac OS X 安装程序（使用 install4j 6.1 构建）在运行 InstallFilesAction。显然它正在尝试使用 AppleScript 但找不到引擎：

[ERROR] com.install4j.runtime.beans.actions.InstallFilesAction [ID 6]: 
java.lang.NullPointerException
        at com.install4j.runtime.installer.helper.AppleScriptHelper.initEngine(AppleScriptHelper.java:30)

        at com.install4j.runtime.installer.helper.RunningProcessChecker$RunningProcessThread.run(RunningProcessChecker.java:329)

有办法解决这个问题吗？

编辑：我还在使用 6.0.4

构建的安装程序上复制了它

这是 JRE 中出现在某些机器上的错误。此异常意味着无法检测到某些进程，但不会影响安装程序。
