What happened to JAXB's NamespacePrefixMapper in JDK6u18

I've been using

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
. 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!


I don't think that the class com.sun.xml.internal.bind.marshaller.NamespacePrefixMapper is a replacement of com.sun.xml.bind.marshaller.NamespacePrefixMapper, the former is there for a long time and it NOT MEANT TO BE USED BY YOU AT ALL (hence the internal packaging).

The problem here is that JavaSE 6 doesn't have the JAXB RI (it has a JAXB implemenation but not JAXB RI) so if you want to rely on RI specific feature, you should bundle JAXB RI in your application (and that would protect you from JAXB changes in Java SE).
