 /*
  * This class should throw VerifyError because the StackMap for bytecode index
  * 45 (astore_2, line 123) is incorrect. The stack maps for bytecode indexes 45
  * and 49 (astore, line 133) do not match because 45 does not supply enough
  * locals to satisfy 49.
  *
  * The astore_2 bytecode at bytecode index 45 changes the type state,
  * preventing the stackmap mismatch.  But, if the incoming type state is used,
  * as required by JVM Spec 8, then the verifier will detected the stackmap
  * mismatch, and throw VerifyError.
