 /**
 63   
  * Wrapper around a <code>Throwable</code> object. Whenever an exception occurs
 64   
  * in a test case executed on the server side, the text of this exception
 65   
  * along with the stack trace as a String are sent back in the HTTP response.
 66   
  * This is because some exceptions are not serializable and because the stack
 67   
  * trace is implemented as a <code>transient</code> variable by the JDK so it
 68   
  * cannot be transported in the response. However, we need to send a real
 69   
  * exception object to JUnit so that the exception stack trace will be printed
 70   
  * in the JUnit console. This class does this by being a <code>Throwable</code>
 71   
  * and overloading the <code>printStackTrace()</code> methods to print a
 72   
  * text stack trace.
