Consider the following code:

public class IfToCase {

    public boolean isAbc(String val) {
        if (val.equals("abc")) {
            return true;
        } else {
            return false;
        }
    }
}

There is a warning hint to convert to switch over strings, which is useless for a single condition.
The description says: "Marks cascades of ifs which can be converted to switch over Strings" - but there is no cascade of ifs, it's a single if. The hint should be offered only when there are at least two conditions (or make it configurable at the Hints page).
