A DESCRIPTION OF THE PROBLEM :
The New Folder button near the top right of a JFileChooser does not become disabled when displaying the contents of a write-protected directory in Java 7. Pressing the New Folder button in this situation appears to have no effect.

REGRESSION. Last worked in version 6u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a directory, removing all write permission to it.
Display a JFileChooser using the Metal Look and Feel.
Change the directory without write permission.

See if the Create New Folder button is disabled.
Press the Create New Folder button.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Create New Folder button is disabled.
Attempting to press the button will not cause any change including the button being depressed.
ACTUAL -
Create New Folder button is enabled.
Pressing the button caused the button to be depressed and caused the FileName text box to change its contents to contain " NewFolder "

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
