Question

Im working on a Chat client that i didnt write the bulk of the code for. It works fine however when someone sends a message it beeps (system error beep) when using Java 7.
Java 6 and below doesn’t have this beep. I cant seem to find whats causing the beep is there any way to find it ?

I dont think its calling beep as i have

public class nobeep extends sun.awt.windows.WToolkit {
    @Override
      public void beep() {
          System.out.println("tried to beep");
          new Exception().printStackTrace();
  }
} 

and then called

 System.setProperty("awt.toolkit", "nobeep");

in the main method.

Using the method to send a beep doesnt make it beep. Its only when sent normally. Is there a quick way to track down the cause of the beep ?

Edit:

After looking in the bugs database – its confirmed.

I know it says no work around but is there one (java not c++) or just wait until update 8 ?

Answer 1

The solution I found was converting awt to swing. I cant find a way to over ride what the fix in the bug report was. Its now working fine in either version
