Question

操作系统：macOS Sierra 10.12.3（16D32）

jxbrowser version：6.14.2

我将jxbrowser cache和logs目录设置为执行的jar文件附近的单个文件夹。当它从头开始运行时异常上升：java.nio.file.NoSuchFileException：... jxbrowser-browser.log.lck

如果运行以前的版本（6.3），然后运行当前版本，那么一切正常。

根据异常堆栈跟踪，错误来自：

ru.mybetter.ui.desktop.BetterClient.redirectLogMessagesToFile(BetterClient.java:174)

我想你创建了FileHandler实例，其中包含一个不存在的文件的无效路径。或者，根据FileHandler(String pattern)的Javadoc，IOException时there are IO problems opening the files可以从其构造函数中抛出FileHandler。

请确保您传递给class a{ public $b=['f'=>'c']; } $a=new a; $b='b'; echo $a->$b['f'];构造函数的文件的路径可以从Java程序访问，并且没有读/写权限问题。

在空文件夹中运行时，JXbrowser初始化失败：java.nio.file.NoSuchFileException：... jxbrowser-browser.log.lck
