我正在使用带有SizeAndTimeBasedFNATP的logback RollingFileAppender。除了翻滚之外，一切看起来都不错。代码是：c.q.l.co.rolling.helper.RenameUtil - 无法在Windows上重命名文件

当我在调试模式下运行同样的程序，我发现是由没有任何错误信息返回false失败的文件类renameTo方法。我在Windows 10上运行我的程序。使用processMonitor（Procman.exe）双击/三重检查以捕获任何持有该文件的进程（application.log）。没有进程保存该文件。下面的输出仍然失败。如何解决这个问题？
