There is a bug in com.sun.xml.bind.v2.runtime.output.NamespaceContextImpl

NamespaceContextImpl reuses NamespaceContextImpl.Element objects to generate prefixes.
NamespaceContextImpl.Element.setTagName(Name tagName, Object outerPeer) doesn't clean up NamespaceContextImpl.Element.elementLocalName
When the element is reused in
NamespaceContextImpl.declareNsUri(String uri, String preferedPrefix, boolean requirePrefix) {
if (current.elementLocalName!=null)

{ // CHANGES A NAME TO THOSE LEFT FROM AN OTHER NODE!!! current.setTagName(size, current.elementLocalName, current.getOuterPeer()); }


Solution is to clean elementLocalName in

public void setTagName( Name tagName, Object outerPeer ) {
assert tagName!=null;
this.elementName = tagName;
this.elementLocalName = null; // +
this.outerPeer = outerPeer;

thank you for reporting. Can you please provide small test case how can I reproduce the problem.

Unfortunately I can't .
Things works to me now and I did too much changes to figure out what was wrong.

I had an adapter with a DOM Element returned.
Somehow JAXB is parsing this element tree using localNames.
IMHO it's obvious that either elementName or elementLocalName must be null.

I got the bug again and finally figured out what exactly happens.
I have a QName attribute.
When the default namespace is defined (i.e. xmlns="www.example.com") and
my QName attribute has no namespace,
NamespaceContextImpl tries to rearrange:

> 188 // first, if the previous URI assigned to "" is
> 189 // a "known URI", remember what we've reallocated
> 190 // so that we can fix it when this context pops.
> 202 if (current.elementLocalName!=null)

{ > 203 current.setTagName(size, current.elementLocalName, current.getOuterPeer()); > 204 }

here it changes the tag name (current).
setTagName has a bug - doesn't clean elementLocalName (as seen above).

P.S. can't find a way to submit jUnit test code.
