JDK-8032518 - fatal error has been detected by the Java Runtime Environment (access violation)
Description
The code does:

  if (result == NULL) {
      free(dcmd_info_array);
      JNU_ThrowOutOfMemoryError(env, 0);
  }
  ...
  free(dcmd_info_array);

JNU_ThrowOutOfMemoryError() does not cause the current function to return (it is not a macro), so free(dcmd_info_array) can be called twice.
