| * 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 |
