// This .jcod test was derived from the following Java program. In the .jcod
// file, The first opcode was changed to an illegal value to cause a 'bad
// 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.
