Re: NULL Pointer exception in BeanDeserializer

[Peter Smith]

A bug detection tool I ran recently identified a possible null pointer 
dereference in this very method. (line numbers don't match exactly but I 
was using 1.2beta3 source code).

The problem detected by the tool related to an unguarded dereference of 
the 'dSer' local var:

                   dSer.registerValueTarget(new BeanPropertyTarget(value,
                           propDesc, collectionIndex))
Unfortunately, I am not at all familiar with the Axis code, nor how your 
scenario has caused this problem, but at least now that there is 
apparently a *real* user problem I hope my earlier bug report may be 
taken a bit more seriously ;-)

See http://issues.apache.org/jira/browse/AXIS-1924

I am passing an input parameter with a forward slash like 
<COMPANYNAME>/<USERNAME>.
This is when I see this exception.
