NullPointerException generating WSDL with anonymous simple types
----------------------------------------------------------------
Key: AXIS2-1867
URL: http://issues.apache.org/jira/browse/AXIS2-1867
Project: Apache Axis 2.0 (Axis2)
Issue Type: Bug
Components: codegen
Affects Versions: nightly
Environment: Axis2 1.1.1-SNAPSHOT (nightly build), JDK 1.5.0_08 x64,
Windows XP x64
Reporter: Peter Runge
WSDL2Java is failing on a WSDL that has multiple anonymous simple types with a
NullPointerException.
This may be related to issue AXIS2-1780, however this WSDL was tried with the
latest nightly build (built 2006-12-13).
The following is output of the error with the nightly build. The same error
occurs with Axis2 1.1.

It seems that removing one of the anonymous simple types allows the code to be
generated without error.
The following WSDL was used (simplest form of original to reproduce bug):
