+ * The test for the implementation of an object of the type     <BR>
+ * ObjectReference.                                             <BR>
+ *                                                              <BR>
+ * The test checks up that results of the method                <BR>
+ * <code>com.sun.jdi.ObjectReference.referenceType()</code>     <BR>
+ * complies with its spec when ObjectReference is StringReference.<BR>
+ * <BR>
+ * The test consequently checks up the following assersions:    <BR>
+ * - the type may be a subclass or implementor of the declared type<BR>
+ *   of any field or variable which currently holds it;         <BR>
+ * - the returned ReferenceType will be a ClassType or ArrayType<BR>
+ *   and never an InterfaceType;                                <BR>
+ * - the type of an object never changes, so this method will   <BR>
+ *   always return the same ReferenceType over the lifetime     <BR>
+ *   of the mirrored object.                                    <BR>
