    Description

      Name: viR10068 Date: 11/03/2003


      The JVM (1.5.0-beta-b26) rejects valid class files with
      the extends clause while the prolog spec accepts it.

      The new JCK tests are failed due to this error:
      vm/cldc/typechecker/rules/rules013/rules01301m1/rules01301m1.html

      The test source:
      --------------------- test07.jasm ---------------------------
      public class test07 extends java/lang/Throwable
              version 49:0
      {
      public Method "<init>":"()V"
      stack 1 locals 1
      {
      aload_0;
      invokespecial Method java/lang/Throwable."<init>":"()V";
      return;
      }

      public static Method run:"([Ljava/lang/String;Ljava/io/PrintStream;)I"
      stack 2 locals 3
      {
      try t0;
      new class java/lang/Throwable;
      dup;
      invokespecial Method java/lang/Throwable."<init>":"()V";
      athrow;
      endtry t0;
      catch t0 java/lang/Throwable;
      locals_map class "[Ljava/lang/String;", class java/io/PrintStream;
      stack_map class java/lang/Throwable;
      astore_2;
      iconst_0;
      ireturn;
      }
      } // end Class test07
