In the JVMTI documentation for GetStackTrace there is a code snippet
outlining how to use the functionality:
jvmtiFrameInfo frames[5];
jint count;
jvmtiError err;
err = (*jvmti)->GetStackTrace(jvmti, aThread, 0, 5,
&frames, &count);
if (err == JVMTI_ERROR_NONE && count >= 1) {
char *methodName;
err = (*jvmti)->GetMethodName(jvmti, frames[0].method,
&methodName, NULL);
if (err == JVMTI_ERROR_NONE) {
printf("Executing method: %s", methodName);
}
}
There are two errors in the code:
1. The 5th argument to GetStackTrace (frames) should not have an ampersand
2. GetMethodName takes 5 parameters, but the example only passes four
parameters to it
Please review the following change:

Thanks,
