`NULL` affects as a loop stopper in `ParseArguments()` as following:
static jboolean
ParseArguments(int *pargc, char ***pargv,
int *pmode, char **pwhat,
int *pret, const char *jrepath)
{
int argc = *pargc;
char **argv = *pargv;
int mode = LM_UNKNOWN;
char *arg;
*pret = 0;
while ((arg = *argv) != 0 && *arg == '-') {
But I'm not sure it is valid, I think it might be discussed as another issue.
