Description

In some Methods of org.apache.cxf.staxutils.W3CDOMStreamReader the DOM Level of the underlying DOM-implementation is checked (e.g. 'getLocation()'), but this is not true for all methods.

The method 'getSystemId' calls 'org.w3c.dom.Document.getDocumentURI()' without handling exceptions/errors from implementations which are not DOM Level 3. When running under Weblogic this results in the following error, which occours when validating the schema for a not schema valid XML structure:
