Hidden directories not excluded - p1

Consider:

final var factory = new JWFilterGlobFactory();

final var filter = factory.create( "PDF files (*.pdf)" )
              .addRule( INCLUDE, "**/*.pdf" )
              .addRule( EXCLUDE_AND_HALT, "**/.*" )
              .build();

final var builder = builder().addFileFilters( filter );
final var config = builder.build();

try( final var chooserType = JWFileChoosers.create() ) {
  final var chooser = chooserType.create( parentWindow, config );
  chooser.showAndWait();

Expected:

• The file chooser opens with File type set to PDF files (*.pdf).
• No hidden files or directories (starting with .) are listed.
• Both "." and ".." directories are listed.
• No option to select all files in the File type list.
• No option to select only directories in the File type list.

Actual:

• The file chooser opens with File type set to All files (*.*).
• User may set File type list to "All files" or "Only directories".
• Hidden files are not excluded from the list.
• Only "." is listed.

Not sure if this is an enhancement or a bug.
