RenameUtil doesn't create create a non-existing destination directory
---------------------------------------------------------------------

                 Key: LBCORE-151
                 URL: http://jira.qos.ch/browse/LBCORE-151
             Project: logback-core
          Issue Type: Bug
          Components: Rolling
    Affects Versions: 0.9.20
            Reporter: Torsten Juergeleit
            Assignee: Logback dev list


RenameUtil doesn't handle moving files into non-existing directories in a robust manner. There's no check if the destination directory is available and writable.
If File.renameTo() fails then it's assumed that this is due to a locked from file. The other reason of a non-existing or non-writable destination directory is not checked (corresponding unit test is attached).

Here it makes sense to create a non-existing directory tree via File.mkdirs().

Otherwise the requirement of an existing destination directory should be clearly stated in the documentation of RollingFileAppender.
