> Functions from Field group of JVMTI functions crashes if it's called with incorrect fieldID. According to specification function should return JVMTI_ERROR_INVALID_FIELDID (25) in this case.
> This occurs because of insufficient check of fieldID in Field group of JVMTI functions. Those functions have no checking of whether field with this fieldID exists.
> Solution to this problem is to add additional checking of fieldID to know whether this field exists. This checking is as follows: take list of _all_ class fields and its IDs and check whether fieldID is in that list before to start working with it.
