Is it safe to sync java.awt.Container.paint (Graphics g)?

I am using some 3rd party AWT components in a desktop application. The component's layout has been changed in the method paint()

and this causes very strange behavior. This seems to have been fixed by adding a keyword synchronized

to the paint () method, but is it safe to do so?

It looks like the method paint()

is being called outside of the event dispatch thread , which can indeed cause very strange behavior, so this should never be done.



Instead, paint()

the application code should only callrepaint()

The paint method should only be called on one thread, the Dispatch Event thread, so there is no need to synchronize. I would guess that the root of the problem lies in how the components are used. Check out this link for some ideas around concurrency in the user interface.
