| // This .jcod test was derived from the following Java program. In the .jcod |

| // instruction' VerifyError exception. Also, the stack map table was changed |
| // so that it contains an illegal verification type. The error occurred when |
| // the verifier tried to print the stack map table as part of the 'bad |
| // instruction' VerifyError exception. |
