[8] Review request for 8021379: JFileChooser Create New Folder button enabled in write proteced directory

[Sergey Malenkov]

Hello,

Could you please review the following fix:
fix: http://cr.openjdk.java.net/~malenkov/8021379.8.1/
bug: http://bugs.sun.com/view_bug.do?bug_id=8021379

The File.Pane.canWrite method must call the File.canWrite method,
not the ShellFolder.isFileSystem.

Thanks,
SAM
