I tested the same program under several environments.

  Java VM     Compiler            Result
  -------     -----------         ----------
  JDK 1.3     kjc-1.5B            java.lang.VerifyError
  JDK 1.3     kopisusu-1.9b5      SUCCESS
  Kaffe(*)    kjc-1.5B            java.lang.NullPointerException
  Kaffe(*)    kopisusu-1.9b5      SUCCESS

   Kaffe(*): Version: 1.0.6

These results make me think KJC has something to do with this issue.
