This bug made me laugh...... easy to fix though.
The issue is that woodstox internally uses a "null" prefix for the default
prefix. When we create the nsMap, we just call:
treeMap.put(pfx, ns)
which, in this case, the pfx is null. If you look at the javadoc for
TreeMap's put call, you see:
* @throws NullPointerException if the specified key is null
* and this map uses natural ordering, or its comparator
* does not permit null keys
so it SHOULD be throwing a NullPointerException at that point. But it's
not. If you actually look at the code for the TreeMap in the JDK, you see
this nice comment:
// TBD:
// 5045147: (coll) Adding null to an empty TreeSet should
// throw NullPointerException
//
// compare(key, key); // type check
So they are actually aware of it. If you look at the comments for that bug:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5045147
"Unfortunately, this fix exposed too many bugs in Other Peoples' Code, so
backed out for now."
Anyway, it's a simple fix for us to not add the null key (we use "" in other
places and for non-woodstox). But I thought I'd mention that it gave me a
little chuckle.
