A DESCRIPTION OF THE PROBLEM :
My XML Digital Signature code runs fine under Java 8 (1.8.0_161), but on upgrading to OpenJDK 11 (11.0.2, ), it now traps with an NAMESPACE_ERR exception:

org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

If I revert back to Java 8 or even Java 10, it works again.

REGRESSION : Last worked in version 8u181


CUSTOMER SUBMITTED WORKAROUND :
Currently, we have to revert from JDK 11 to Java 8 or 10.

FREQUENCY : always
