Is fixed by changing implementation of
org.apache.ws.commons.util.NamespaceContextImpl.endPrefixMapping to:
public void endPrefixMapping(String pPrefix) {
if(pPrefix.equals(cachedPrefix)) {
cachedPrefix = cachedURI = null;
} else {
for(int i = 0; i < prefixList.size(); i += 2) {
if(prefixList.get(i).equals(pPrefix)) {
prefixList.remove(i);
prefixList.remove(i);
return;
}
}
throw new IllegalStateException("The prefix " + pPrefix + " was
not defined.");
}
}
