Question

 public int getFreezeColumns() {
    Integer currentValue = (Integer) checkValueBinding("freezeColumns", this.freezeColumns);
    if (currentValue != null) {
      return currentValue;
    }
    return 0;
  }

FindBugs says :

A primitive is boxed, and then immediately unboxed. This probably is due to a manual boxing in a place where an unboxed value is required, thus forcing the compiler to immediately undo the work of the boxing.

How can I possibly fix this ?

Answer 1

I think the complaint is somewhat misleading: you are not boxing the return value of checkValueBinding which is an Object, but you are casting it to Integer prematurely

Try changing the code to see if it helps you avoid the warning:

public int getFreezeColumns() {
    Object currentValue = checkValueBinding("freezeColumns", this.freezeColumns);
    if (currentValue != null) {
        return (Integer)currentValue;
    }
    return 0;
}
