Are this text more clear than my version? I create it using the text forms/terms which
are already present in the javadoc.

The text where we describe bounds/location optionality:
  126  * Note: the location and size of top-level windows (including
  127  * {@code Window}s, {@code Frame}s, and {@code Dialog}s)
  128  * are under the control of the desktop's window management system.
  129  * Calls to {@code setLocation}, {@code setSize}, and
  130  * {@code setBounds} are requests (not directives) which are
  131  * forwarded to the window management system.  Every effort will be
  132  * made to honor such requests.  However, in some cases the window
  133  * management system may ignore such requests, or modify the requested
  134  * geometry in order to place and size the {@code Window} in a way
  135  * that more closely matches the desktop settings.

The new text about visual perception:
  137  * The visual appearance and behavior of top-level windows (including
  138  * normal/shaped/translucent/undecorated {@code Window}s, {@code Frame}s,
  139  * {@code Dialog}s) are under the control of the desktop's window management
  140  * system. The visual effects as shadows, motion effects, animations,
  141  * and others may not be controlled by the applications but work according to
  142  * the desktop settings.

Both look aligned.

Best regards, Sergey.
