Opening the OS-supplied File Manager (other than Nautilus) fail

[tudogeorge]

Commands that require launching the OS File Manager fail with the following exception:
java.io.IOException: Cannot run program "nautilus": error=2, No such file or directory.

I tried

• File > Reveal on Desktop
• File > Include > Reveal in Explorer

Expected Behavior

The OS-supplied File Manager application should open at that file's location and with that file selected.

Current Behavior

The following exception is thrown: java.io.IOException: Cannot run program "nautilus": error=2, No such file or directory.
The error message popping up at "Reveal in Explorer" is misleading (it says "File cannot be found" instead of "Could not reveal / ".

Steps to Reproduce

• On a Linux distribution with a file manager other than Nautilus, open the Scene Builder application
• Create and save an FXML file (CHILD_FILE.FXML) - do not close Scene Builder
• Reproduce the issue on "Reveal on Desktop" by accessing File > Reveal on Desktop
• Create and save another FXML file (PARENT_FILE.FXML) - this instance can be closed
• Include CHILD_FILE.FXML into PARENT_FILE.FXML
• In the left-hand side of the editor, in the Document > Hierarchy section, select the included file
• Reproduce the issue on "Reveal in Explorer" by accessing File > Include > Edit 'CHILD_FILE.FXML' in Explorer
