+ |                              DESCRIPTION                                   |
+ First, modify an XSP sample included in the distribution to throw a runtime 
+ exception during the execution of the constructor. Let's pick simple.xsp in the 
+ docs/samples/xsp/.
+ 
+ Add the following codes directly below the <xsp:page> tag:
+ 
+    <xsp:logic>
+       String a = parameters.getParameter("data-dir", ".");
+    </xsp:logic>
+ 
+ That will cause a runtime exception is thrown since the variable 'parameters' 
+ is not initialized at the time of the initialization of the variable 'a'.
+ 
+ After doing this, if we don't remove the contents of work directory manually, 
+ the XSP page won't reload even though we remove the above lines.
+ 
+ Also this bug indicates that there should be a way to handle exceptions 
+ occuring in the course of instance initialization. At this time, no messages 
+ are provided even though NullPointerException is thrown. I spent a whole day to 
+ figure out what's wrong, without knowing that it's because of the initial 
+ trivial bug that was fixed earlier.
+ 
+ Thanks...
