Hello everyone,

I'm facing rather a strange error when running Jboss 15.0.1.Final on Java 11 (OpenJDK).
I'm attempting to send a SOAP message via a client generated from WSDL (generated via apache CXF).

The stacktrace:

```

Interceptor for {anUrl}XXX#{anUrl}XXX has thrown exception, unwinding now: org.w3c.dom.DOMException: WRONG_DOCUMENT_ERR: A node is used in a different document than the one that created it.

```

In a case i deciede to unit test the library alone, everything works.

if i migrate my entire environment back to Java 8 this SOAP call works fine.

I tried to manually update cxf libraries within the package wildfly-15.0.1.Final/modules/system/layers/base/org/apache/cxf to more recent version, but the issue remained.
