Structural Search Inspection not working for Structural Search that does?

Hello, All -

If I issue this Structural Search:

$field$ = $something$;
if ($field$ == null) {
     throw new ServletException($msg$);
}

with all default constraints via Edit > Find > Search Structurally, it matches code you'd expect it to, e.g.,

metricId = inputForm.getMetricId();
if (metricId == null) {
     throw new ServletException("Missing metricId");
}

If you dump this into a Structural Search Inspection as a Search Template, it doesn't flag this same code. (All of my other SS Inspections work great - I love this feature!)  Ideas?

Thanks in advance,
- Luke
