How to tell infer to not to report the specific error in specific location

I use facebook infer to detect error in my Android project. It find some error but is not error.

try {
...
AppInfo app = JsonUtil.parseObject(resFileContent , AppInfo.class);
app.setAppPackagePath(simpleInfoFile.getParent());
return app;
} catch (Exception e) {
e.printStackTrace();
return null;
}
infer report the error

132: error: NULL_DEREFERENCE
object app last assigned on line 130 could be null and is dereferenced at line 132
130. AppInfo app = JsonUtil.parseObject(resFileContent , AppInfo.class);
131.
132. > app.setAppPackagePath(simpleInfoFile.getParent());
133. return app;
134. } catch (Exception e) {
135.

The NullPointerException will be caught by try...catch... so it is not an error. How to tell infer not to report the error or ignore check in this line?
