Bill Mitchell reopened AXIS2C-675:
----------------------------------
This problem has been encountered again recently, and it appears to me there is
a real issue in axiom_node_detach and how it is used. Consider the case of a
SOAP response message in which the server declared the namespaces at one of the
outer elements. Where a wsdl declares an element of type any, not knowing the
underlying structure, the generated adb classes detach the node and its subtree
and makes the tree available to the client app. The client app may choose to
retain the response structure and the returned object tree for later use. Yet
the upper levels of the om will be discarded when the SOAP response message is
discarded upon the next request through the service client. And, thus, Axis
will free the namespaces underneath the adb objects.
It hardly seems fair to place the responsibility on the creator of the tree not
to release the namespaces underneath the detached node, when the tree is
created as the SOAP message is parsed, and the location of the xml namespace
declaration in the message is determined by the other side of the exchange.
An alternative fix is to re-declare the namespaces on the node being detached,
to ensure that it and its children remain valid regardless of what happens to
its former parent tree. Re-declaring the namespaces will cause the ref counts
in the namespaces to be incremented, and thus the namespace structures will be
retained until both the former parent tree and the detached node tree are
released.
