+ * @summary Verifies that java.lang.AbstractMethodError is not thrown when
+ *          serializing improper version of DocumentImpl class as reported in XERCESJ-1007.
+ *          Test preconditions and steps:
+ *          - Compiles test version of org.w3c.dom.Node and org.w3c.dom.Document
+ *          - Compiles DocumentImpl overriding java.xml module with Node and Document
+ *          - Runs AbstractMethodErrorTest overriding java.xml only with DocumentImpl class
+ *            Hence, the interfaces compiled in the first step need to be removed
+ *            from the test folder in order to reproduce the bug scenario. At the time of writing,
+ *            the clean command was not able to resolve paths generated by compile/module
+ * @library /test/lib
+ * @compile --patch-module java.xml=${test.src} org/w3c/dom/Document.java
+ * org/w3c/dom/Node.java com/sun/org/apache/xerces/internal/dom/DocumentImpl.java
+ * @clean org.w3c.dom.*
