OK... Tried that. Still the same thing. There's not much to my code, so
I'm including it below. Please let me know if you see anything.
Thank you for helping me,

System.err.println("Starting: " );
System.out.println("I'm starting...");
try{
// Create file

BufferedWriter out = new BufferedWriter(fstream);
out.write("Hello Java");
//Close the output stream
out.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
throw new IOException() ;
}
@Invalidate
public void stop() {
System.out.println("I'm leaving !");
}
