| hseigel@7666 | 26 | * This class should throw VerifyError because the StackMap for bytecode index |
| hseigel@7666 | 27 | * 9 (dstore_2, line 60) is incorrect. The stack maps for bytecode indexes 9 |
| hseigel@7666 | 28 | * and 18 (astore_2, line 70) do not match because 9 does not supply enough |
| hseigel@7666 | 29 | * locals to satisfy 18. |
| hseigel@7666 | 30 | * |
| hseigel@7666 | 31 | * The dstore_2 bytecode at bytecode index 9 changes the type state, |
| hseigel@7666 | 32 | * preventing the stackmap mismatch. But, if the incoming type state is used, |
| hseigel@7666 | 33 | * as required by JVM Spec 8, then the verifier will detected the stackmap |
| hseigel@7666 | 34 | * mismatch, and throw VerifyError. |
