Subject NullPointerException after upgrade to 2.3.2
Date Tue, 15 Jul 2008 17:24:59 GMT
I just upgraded to 2.3.2 due to the fact that Spring 2.5.5 seems to need 
it. After I upgraded I am now getting a NullPointerException after 
executing a procedure. This was working prior to the upgrade and seems to 
be associated to the TypeHandlerFactory.setTypeHanlder method at line 143. 
As I step through the code it appears that the result is returned from the 
procedure. I can see the value returned and my CustomTypeHandler is being 
invoked and is returning the correct value.  ('N' == Boolean.FALSE)

It appears this error begins in the class ComplexDataExchange.setData() 
method. On line 95 the following statement is executed:

(typeHandlerFactory.hasTypeHandler(parameterMap.getParameterClass())) {

However, my parameterMap has no parameterClass specified and when it is 
retrieved a null value is returned. This causes the NullPointerException 
to occur in the TypeHandlerFactory.setTypeHanlder() method at line 143:

if (handler == null && Enum.class.isAssignableFrom(type)) {

The test is made to see if the handler is null but no test is performed to 
see if the type is null and this results in the NullPointerException.

Is it now required to have a ParameterClass specified on every statement?
