This is because the Java version uses a c14n object from xmlsec to do the
output to string, and that strips the extra namespaces in some cases.

The problem may be namespace-related, but not due to anything you posted.
Exclusive c14n happens before verification anyway. More likely either you
added a namespace somewhere without telling the library about it, or
something is corrupting the XML before or after you're encoding it.
