What happened to JAXB's NamespacePrefixMapper

Question

I've been using com.sun.xml.bind.marshaller.NamespacePrefixMapper in my project, and i had no problem with it in JDK 6u17. Now I just updated to 6u18, and I saw that it has been replaced to com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper. However if I import this class and try to compile my classes, I get the error:

package com.sun.xml.internal.bind.marshaller does not exist
import com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper;

I can access this package through the NetBeans code completion feature, and NetBeans does not highlight the code for errors.

Any help would be appreciated!

Sun had made something not quite appropriate in this case. The namespace mapper isn't included in the spec, but it is "advertised" as a way to customize prefixes. So the general advice "don't use com.sun.*" doesn't apply here, and the javadoc of this class says:

Implemented by the user application to determine URI -> prefix mapping.
