I believe a sealing violation means you have a "sealed" package (i.e. a
package in a library whose manifest specifies that all classes for that
package must be loaded from the same library), but for some reason, an
attempt is being made to load different classes from the package from
different libraries.

My guess would be you have more than one DOM implementation on your
classpath, and that's the source of the problem.
