      The JVM (1.5.0-beta-b26) rejects valid class file with
      exception. Note, the prolog spec accepts this class.

      The new JCK tests are failed due to this error:
      vm/instr/aaload/aaload003/aaload00301m1t/aaload00301m1t.html

      The test source:
      --------------------- test03.jasm ---------------------------
      public class test03 version 49:0 {

      public static Method run:"([Ljava/lang/String;Ljava/io/PrintStream;)I"
