JavaFX code allows updating the UI from an JavaFX application thread. But from the above exception message it says that it is not using FX Application thread . One way you can fix is to launch an FX Application thread from the resetPage method.
Outside it, inside the while loop, add Thread .sleep(1000) The reason behind Illegal State Exception is you are trying to update UI on some thread other than JavaFX Application thread . The reason why your app was crashing when you added it was you were overloading the UI thread by adding a process to be executed on the UI thread infinitely.
