So basically, when I write something like:  \r\n```java\r\nPreconditions.checkArgument(item != null, \"Unable to find an element with name '%s'.\", name);\r\nreturn item;\r\n```\r\n`item` is null safe, but NullAway still raises an error.\r\n\r\n![image](https://user-images.githubusercontent.com/9077612/32056349-b8ae8a6a-ba64-11e7-9029-6b522346f238.png)\r\n"}}
