MouseEvent.CTRL_MASK is being masked as MouseEvent.SHIFT_MASK

Question

I am working on a legacy Java App that was written in the 1.1 era. We have recently upgraded enough components and keywords so that the applet is now compiling and executing under JDK 1.5 but it seems that the CTRL + Mouse click action is being masked as a SHIFT + Mouse click on our table model. I have added the snippet that I am using to verify this.
Does anyone know of a reason for this behaviour or have come across it in their own upgrades to 1.5
Thnx,
int mod;
if ((mod = e.getModifiers()) > 0) {
  switch (mod) {
     case MouseEvent.CTRL_MASK:
          System.out.println("Got CTRL Click");
          break;
     case MouseEvent.ALT_MASK:
          System.out.println("Got ALT Click");
          break;
         //CTRL + Click always resolves to this case event
     case MouseEvent.SHIFT_MASK:
          System.out.println("Got SHIFT Click");
          break;
} else {
     System.out.println("Mod is: " + mod);
}

Answer 1

My apologies, seems as though my test case is obviously flawed. With no default case, seems my debugger is stopping on shift click because I am not checking for the right type of variable.
Thnx anyway,
