Try FileChooserDemo to invoke standard open and save filechooser dialogs in different look and feels. In metal L&F, there are extra mnemonic keys (X) displayed on button labels. In nimbus Look and Feel, there is extra (S) on save button. Please refer to the attached screenshots.

This may also happen on other platforms.

In b133, there is no such problem. This is a regression.

I looked through current CRs related with mnemonic issues and it seems that this problem was not filed in other CR.
