Reports equals() being called to compare a String with an empty string. In this case, using .isEmpty() is better as it shows you exactly what you're checking.

Example:

After the quick-fix is applied:

"".equals(str) returns false when str is null. For safety, this inspection's quick-fix inserts an explicit null-check when the equals() argument is nullable. Use the option to make the inspection ignore such cases.
