Trying to use the fillInStackTrace method

Question

Hello,
The following code generates an error when I try to compile it.
  private void divide() throws Exception
    try
      double a = 50/0;
    catch (Exception error)
      throw error.fillInStackTrace();
And it's called from:
  void jButton1_actionPerformed(ActionEvent e)
    try
     divide();
    catch (Exception error)
      error.printStackTrace();
  }What's wrong ?
The error is:
Error #: 360 : unreported exception: java.lang.Throwable; must be caught or declared to be thrown at line ...
As you see, I just capture the exception and try to redispatch it.
Thanks in advance,
-- Lelio.

Try this:
private void divide() throws Throwable
try
double a = 50/0;
catch (Exception error)
throw error.fillInStackTrace();
void jButton1_actionPerformed(ActionEvent e)
try
divide();
catch (Throwable error)
error.printStackTrace();
The fillInStackTrace throws a Throwable object, which Exception extends, not the other way round. So catching an Exception does not catch a Throwable, but catching a Throwable does catch an Exception.
