InstantiationError using abstract types
---------------------------------------
Key: AXIS2-4117
URL: https://issues.apache.org/jira/browse/AXIS2-4117
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: databinding
Affects Versions: 1.4.1
Environment: axis 1.41, jdk 1.5.0_16
Reporter: juergen schad
Priority: Critical
We are using jaxb-databinding and unmarshalling of requests fails during
processing of nodes with
abstract base-classes. Unmarshalling of types with complexContent works fine
but unmarshalling of types
with simpleContent doesn't work at all. The attached example-wsdl and this
sample request shows the problem.

Unmarshalling of the tst:testMember-node suceeds, the given xsi-type is used to
create an instance of the matching type.
Unmarshalling of the tst:Test-node fails, the given xsi-type is ignored and the
instantiation of the abstract baseclass STE_TestAbstract
fails with an InstantiationError
