}

The path seems alright and i can't figure there's anything wrong with my controller source let me know if anyone want to see the source. How can i fix this unknown Exception ?

Several things to keep in mind

  • Java version is

    openjdk version "1.8.0_151"

    OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.17.10.2-b12)

    OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

  • I'm using Netbeans IDE with all javafx plugins installed.

Solution

  • Sorted this out by installing Java 9.0.4 and Intellij IDE. Netbeans 8.2 isn't compatible with java 9. The code was all right.

    UPDATED CODE

    The controller source has been updated to make it compatible with java9. For some reason java.nio.file.Paths; isn't working with the latest java.
