Description of problem: A program from *Curach's Java SE6* book does not compile correctly. Version-Release number of selected component (if applicable): $ gcj --version gcj (GCC) 4.4.3 20100127 (Red Hat 4.4.3-4) Copyright (C) 2010 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. How reproducible: Easy Steps to Reproduce: 1. Enter the following code through your favorite editor and save it: import java.util.Scanner; public class InvoiceApp { public static void main(String[] args) { // Welcome the user to the program System.out.println("Welcome to the InvoiceTotal Calculator"); System.out.println(); // create a Scanner object named sc Scanner sc = new Scanner (System.in); // perform invoice calculations until choice isn't equal to "Y" or "y" String choice = "y"; while (choice.equalsIgnoreCase("y")) { // get the invoice subtotal from the user System.out.print("Enter subtotal: "); double subtotal = sc.nextDouble(); // calculate the discount amount and total double discountPercent = 0.0; if (subtotal >= 200) discountPercent = .2; else if (subtotal >= 100) discountPercent = .1; else discountPercent = 0.0; double discountAmount = subtotal * discountPercent; double total = subtotal - discountAmount; // display the discount amount and total String message = "Discount percent: " + discountPercent + "\n" + "Discount amount: " + discountAmount + "\n" + "Invoice total: " + total + "\n"; System.out.println(message); // see is user wants to continue System.out.print("Continue? (y/n): "); choice = sc.next(); System.out.println(); } } } (I used Eclipse, so I ended up with a src and bin folder for my project). 2. Use javac to compile this source. Test it and observe the expected program behavior. 3. Now, use the following command to compile the source into a stand-alone executable: $ gcj --main=InvoiceApp -o bin/InvoiceApp src/InvoiceApp.java Observe that no error or warnings are thrown in the compile. Actual results: When the compiled object is run, the program is stopped after the "Welcome" message is displayed and is waiting for input. Pressing <enter> encourages the program to continue. Then, when entering a whole number, the program throws an exception: $ bin/InvoiceApp Welcome to the InvoiceTotal Calculator <enter> Enter subtotal: 100<enter> Exception in thread "main" java.util.InputMismatchException: "" is not a double at java.util.Scanner.myNextDouble(libgcj.so.10) at java.util.Scanner.nextDouble(libgcj.so.10) at InvoiceApp.main(InvoiceApp) Expected results: The compiled program should behave as the javac compiled version.

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
