Oliver Heard commented on AXIS2-4445:
-------------------------------------
This is an odd one because with a particularly complex WSDL I have the NPE is
caused only on 1.6.2 and NOT on 1.6.1. Whereas the example AAR uploaded by
Detelin causes the error on both 1.6.1 and 1.6.2 (which is a much simpler
example) .Unfortunately I can't provide the complex WSDL due to an NDA.
The complex WSDL I mentioned above was generated by the .NET web services
platform. It looks like this is related to the way .NET generates wrapped
arrays, which may help in reproducing the issue.
If I'm successful in producing an equivalent WSDL that causes the 1.6.2 NPE and
not 1.6.1 I'll update this post.
I've included the stack trace given by 1.6.2 below:

> Reason seems to be that the type table is searched for a complex type e.g.
> Data$Number, while it should be Data_Number (replacing the dollar character
> with an underscore).
