Hello,

could you please help me to understand, what might be wrong with my current setup. Piketimer is bailing out with the following error:

OOPS! jar:file:/Users/imorozov/Downloads/PikaTimer-1.5.jar/Pikatimer.jar!/com/pikatimer/FXMLpika.fxml

java version:

[imorozov@1060-imorozov PikaTimer-1.5.jar ]$ java -version
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)

command line:

Odd. It is blowing up on the following line in the results controller: autoUpdateProgressBar.progressProperty().bind(autoUpdateTask.progressProperty()); But the kicker is that has to be on the FX Application thread since the stuff just above the Task creation is also on the app thread.

I have seen this before in FX bugs. Try JDK 1.8.0_171 (which I still have) to see if the issue persists.
