The current spec for Frame.setExtendedState() states:
Note that if the state is not supported on a given platform, nothing will
happen. The application may determine if a specific state is available via
the java.awt.Toolkit#isFrameStateSupported(int state) method.
It's unclear what "nothing will happen" mean - in particular, whether
the value of the state property (as returned by getExtendedState()) will
also not change if the particular state is unsupported.
Also, it seems that the @see link to that Toolkit method is incorrect.

Additionally, according to Denis, only the negative result of the Toolkit check
is 100% correct; if isFrameStateSupported() returns true, the window management
system may still not support the requested state. This should also be made clear
in the spec.

[JDK-6234439] Ambigious spec for Frame.setExtendedState()
BT2:EVALUATION
It would be worth fixing the CR 4633463 at the same time.

metacity doesn't follow the wm spec in case _NET_WM_ALLOWED_ACTIONS protocol.
It says that it supports it, but most of windows do not have it sets. There is a bug against metacity (http://bugzilla.gnome.org/show_bug.cgi?id=115247) which was/will be
fixed in metacity >= 2.19.3

This method does nothing and returns:
public synchronized void setExtendedState(int state) {
if ( !isFrameStateSupported( state ) ) {
return;
}
Extended state of the Frame will not change.

Before setExtendedState was added, this API followed "beans" pattern - you get what you set. Right now, both setState and setExtendedState first check if the state is supported, and then set it. "Nothing will happen" in this case means that neither property value nor state of the Frame is changing. This applies both to setState and setExtendedState. The comments need to be updated for both methods

CR 4977351 also requires spec clarification. Worth fixing together.
