I actually put a wrapper class around JProgressBar to make it thread safe. I was very annoyed that I couldn’t use it from a Swing Worker with informative text messages.

Works like a charm now.

Really have enjoyed the quality of this web site.

Cheers.

If the purpose is only to format dates, I suggest to use the FastDateFormat (or the DateFormatUtils static utility wrapper class). It’s a straightforward replacement for SimpleDateFormat, said to perform faster and thread-safe. By the way this library is full of other very usefull utilities, I always add it to my projet, you should give it a look !

You could also write a wrapper class that has a parse and format function which delegates to the member date format. I’d imagine that it’s not often that you’ll be using many additional methods and it’s not usually critical that your class be a true DateFormat since you’d rarely be substituting various DateFormat instances.

I’ve got one called SynchronizedSimpleDateFormat.
