Bug Description:
JFileChooser accepts illegal filenames

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When you enter a filename or path in the JFileChooser dialog it should not be possible to enter a filename with illegal characters like : * ?

ACTUAL -
JFileChooser does not let you select files containing the illegal characters * and ?
But JFileChooser DOES let you select a file with : (colon)

This leads to some subsequent errors:
- when you try to write to a file named "sample:file" java acutally creates the file "sample" but does not write any content and does not throw an Exception either.
- if you call getCanonicalPath() on the File object ("sample:file") returned by the JFileChooser, java throws an Exception:
java.io.IOException: Die Syntax f?r den Dateinamen, Verzeichnisnamen oder die Datentr?gerbezeichnung ist falsch
at java.io.WinNTFileSystem.canonicalize0(Native Method)
at java.io.Win32FileSystem.canonicalize(Win32FileSystem.java:396)
at java.io.File.getCanonicalPath(File.java:559)
