Oleg Ananiev commented on AXIS2-2796:
-------------------------------------
Looks like I found the problem.
I upgraded to 1.2 but kept axis2.xml that I was using in 1.1.1. Somehow, when I
changed it to the default one supplied with 1.2, my service started to work.
I am not sure what is the difference between the two files but maybe you should
consider mentioning it in the release notes
Best regards,
Oleg

> I have a complex type in WSDL with attribute marked as use="optional". I am

> WSDL2Java. When I do not set this attribute explicitly in my service (its
> value is null), I am getting NullPointerException. When this attribute is

> I am porting my app from Axis2 1.1.1 to 1.2. I have re-generated all my Java
