      Name: szC45993 Date: 03/12/97



      The Java Virtual Machine, chapter 5 Constant Pool Resolution,
      section 5.1.1 Current Class or Interface Not Loaded by Class Loader, claims:

      "3. The class C is linked ($2.16.3), that is, it is verified ($4.9) and prepared.
       ...
         b. ...
       ...
      If a class that is not declared abstract has an abstract method, class resolution throws an AbstractMethodError."

      Meanwhile, undermentioned test gives the following result (jdk_1.1.1):

      java.lang.InstantiationError: javasoft/sqe/tests/vm/constantpool/ClassInterf016/ClassInterf01601/clss
