It's not redundant. Please see my message below in the quote for
details.
Do you mean the following quote:
However, your fix effectively disallows a component to belong to any
toolkit other than the default one, because its getToolkit() will
never return anything else (unless you extend the component's class
and override the method).
? Extending the Component class and providing different implementation
for getToolkit() is the way to achieve this functionality. Without this
extension, it doesn't matter if Component.getToolkit() calls to the peer
or directly returns the default toolkit.
I can't say I fully agree with that. When using the default toolkit, you
don't need to extend public AWT classes. I don't see why you would have
to do that when using a custom toolkit.
Sorry, I still don't get it... To me it looks like we don't change
anything. The current behavior is preserved, Component.getToolkit()
returns the default toolkit. Ability to extend the Component class and
change getToolkit() is not affected. All the weird cases like
co-existence of two different toolkits in the same process, or component
peers that are not created by the current toolkit, etc. are not worth
thinking about to me.
Could you provide a sample, which works with the current implementation
and won't work after the proposed fix, please?
Thanks,
Artem
Can we file a separate P4 issue to evaluate this later, and only change
the specification with 7081584 ?

Hi Sergey,
I'm wondering what compatibility impact of this change is. The
specification for Component.getToolkit() suggests that in theory
several toolkits may co-exist in a single application. And thanks to
delegating to the ComponentPeer, the Component.getToolkit() could
return the actual toolkit for this component.
However, your fix effectively disallows a component to belong to any
toolkit other than the default one, because its getToolkit() will
never return anything else (unless you extend the component's class
and override the method).
I really don't know whether this is widely used, but I think this
may
impact some applications.
Also, imagine a window is made to belong to another toolkit somehow,
even with your changes. Now, why should its ability to be
always-on-top depend on the default toolkit instead of the window's
own toolkit?

Hello,
Could you please review the following fix:
fix:http://cr.openjdk.java.net/~malenkov/7081584.8.0/
bug:https://bugs.openjdk.java.net/browse/JDK-7081584
The specification of the Window class waits for CCC approval. This
fix
removes the getTookit method from the ComponentPeer class and its
subclasses.
Thanks,
