encapsulating unchecked exceptions

[Vladimir R. Bossicard]

While browsing the code (and trying to understand it) I've seen a lot of 
code like this one:

  public void methodname() throws XMLDBException {
    code_that_can_throw_exeception;
  }
Should we encapsulate the call between a try/catch block, like this:
  public void methodname() throws XMLDBException {
    try {
      code_that_can_throw_exeception
    } catch (Exception e) {
      throw new XMLDBException(ErrorCodes.UNKNOWN_ERROR, e);
    }
  }
To respect the signature (and since we have chained exceptions)?  This 
is of course only applicable for unchecked exceptions.
