How to detect when main thread freeze GUI in java?

Question

I want to detect when some time consumption operations in main thread cause gui freeze. My target is to set and unset wait cursor automatically.

thanks

I think you're putting the cart before the horse: Your main thread shouldn't do any time-consuming operations in the first place - they should always be externalized in separate threads, so that your GUI can stay responsive (and e.g. show status on the operations, or provide the possibility to abort them).
