* This class should throw VerifyError because the StackMap for bytecode
* index 45 is incorrect. The stack maps for bytecode indexes 45 and 49 are
* incompatible because 45 doesn't 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.
