StaxUtils.copy(XMLStreamReader,XMLStreamWriter) does not preserve empty
namespace URIs
--------------------------------------------------------------------------------------
Key: CXF-3493
URL: https://issues.apache.org/jira/browse/CXF-3493
Project: CXF
Issue Type: Bug
Components: Core
Affects Versions: 2.4
Reporter: aaron pieper
StaxUtils.copy(XMLStreamReader,XMLStreamWriter) fails to copy documents
correctly if they declare a namespace with a zero-length URI. In some cases,
this URI is frivolous, but in other cases it is important, such as in the
following document:
<foo xmlns="http://example.com"><bar xmlns=""/></foo>
StaxUtils will remove this zero-length URI, resulting in the following XML
document:
<foo xmlns="http://example.com"><bar/></foo>
These two documents are not equivalent. In the first document, bar assumes the
"empty namespace". In the second document, "bar" assumes the example.com
namespace.
