SwingWorker vs BackgroundWorker

In C# I came across Backgroundworker component for concurrency. Although it was slightly advanced than using a plain vanila thread, I found it to be much smoother.

I have not used SwingWorker in Java yet. While doing some coding on threads I came across this reference from JavaDoc for SwingWorker as a solution for threadsafety when working with swing objects.

Question: In C# I don't recall a statement like "not threadsafe for WinForm/WPF layouts, so use BackgroundWorker". I want to know if SwingWorker can be a substitute for threads in all aspect in Java, like how BackgroundWorker is used in C#?

For a novice, should I expect same performance/smooth running/full debug support for SwingWorker?

While a SwingWorker, which implements Runnable, Future and RunnableFuture, can be used anywhere a Runnable or Future is used, no, I wouldn't do this. A SwingWorker is a bit more complex to set up and use vs. a basic Thread/Runnable, and you would have no benefit to using it in non-Swing situations. The SwingWorker has been built to allow for creation of background threads while at the same time ensuring that certain portions of its code is called on the Swing event thread. When run in an application without a Swing event thread, this has no meaning.

Edit
You state:

That means a proper Swing based application has a combination of SwingWorker and basic Thread/Runnable for it to run smooth.

Where do you derive this from my statements above. Your statement doesn't make sense and is certainly not what I have stated above.

That's just useless and the reason I paid more attention - because it was directed by JavaDoc with the basis "Swing isn't threadsafe".

Which is also true of most all GUI libraries.
