Suspicious is that when i try to move FXML file to different packages in eclipse I get this message dialog error: An internal error occurred during: "Search progress polling". Invalid thread access

Not sure about the Eclipse error, but I think you need `getResource("/com/root/tomaszm/MainRoot.fxml")`, with the structure you have. `com.root.tomaszm` is a package name, not a folder name. — James_D, Jan 28 '15 at 22:49

FXML throws that error when it cannot find the FXML document you wish to load.

Looking at the screenshot, this looks like it should get you past the error you're experiencing:

Parent root = 
FXMLLoader.load(getClass().getResource("/com/root/tomaszm/MainRoot.fxml"));
