Daniel Kulp commented on CXF-4183:
----------------------------------
Any chance you could replace your call to StaxUtils.createXMLStreamWriter(new
DOMResult(doc)) with something like:
{code}
new org.apache.cxf.staxutils.W3CDOMStreamWriter(doc);
{code}
and test that? If that works, I'll update the createXMLStreamWriter(Result)
method to check for DOMResult and return that instead. We already do that for
all the createXMLStreamReader calls due to buggy DOM readers, doing that for
the writers may make some sense.
