Verified in 7u10 b18 with the applet and JFileChooser dialog from it. Screenshot is verification-8003284.tiff
                                     

I have re-opened the bug (request from Tracy) because, as Yong reported, the fix do not work well.
                                     

fix failed, not a stopped, please defer
                                     

Please open a new bug for the new Web Start issue. The bug as described in the master bug is fixed.
                                     

I'm re-marking this as fixed, since this change had nothing to do with Web Start -- only applets. We initially thought the change wasn't needed for Web Start, but it looks like we need a new bug.

                                     

It seems that the fix does not work. I install DMG file of 7u10 b17 JRE and open http://docs.oracle.com/javase/tutorialJWS/uiswing/components/ex6/JWSFileChooserDemo.jnlp from safari. When open the filechooser  dialog, the file name with Chinese is not in the list.

If I directly open the JNLP file with javaws in command line, then the file with Chinese name is displayed in the list at file  chooser dialog.
                                     

Attached screenshots:
jnlpcommand: open the jnlp with javaws in command line, file with chinese name is in the list on file chooser dialog.
jnlpsafari: open the jnlp by clicking the button on the webpage in safari. Same JRE, but file with chinese name is not in the list on file chooser dialog.
