WSS4J Invalid Security header -- wish to turn off "ec" prefix in InclusiveNamespace element - wss4j

Question

When hitting a producer web service with the following SOAP request I get a "invalid security header" message returned. When my test case with Oracle JDK 7, which uses JAX-WS RI 2.2.4-b01, it works fine.
I have to use WSS4j 1.6.0 and IBM JDK 6 as I am on Websphere -- I think the problem is with JAX-WS RI 2.1.6 that comes with IBM JDK 6.
I am trying to get my InclusiveNamspaces to look as follows without the "ec" prefix, as I notice this is one of the things different in the XML request shown below.
<S:Header>

<InclusiveNamespaces xmlns="http://www.w3.org/2001/10/xml-exc-c14n#"
PrefixList="wsse S urn urn1" />
But instead it is coming out with the "ec" prefix
<ec:InclusiveNamespaces PrefixList="wsse S urn urn1" xmlns:ec="http://www.w3.org/2001/10/xml-exc-c14n#" />
I have tried this in my code but it does not remove it. Any ideas?
org.apache.xml.security.Init.init();
org.apache.xml.security.utils.ElementProxy.setDefaultPrefix("http://www.w3.org/2001/10/xml-exc-c14n#", "");
