Using JBoss 4.0.3 wsee webservice stack and webservices with attachments. When the webservice receives a request that uses a javax.xml.transform.Source as one of the method arguments a NullPointer is hit in the JavaUtils convert code.

Here is the error:
2006-06-21 03:00:23,116 ERROR [org.jboss.axis.providers.java.RPCInvocation] java.lang.NullPointerException
java.lang.NullPointerException
at org.jboss.axis.utils.JavaUtils.convert(JavaUtils.java:405)
at org.jboss.axis.providers.java.RPCInvocation.prepareFromRequestEnvelope(RPCInvocation.java:332)

Note I have already filed a defect that with a potential workaround:
