Sonar: Security - Array is stored directly

When we get this Sonar critical violation "Security - Array is stored directly", means that an array is being stored directly, e.g:

public void setInventoryClassId(String[] inventoryClassId) {
  this.inventoryClassId = inventoryClassId;
}

In order to solve this issue, we must do the following:


public void setInventoryClassId(String[] newInventoryClassId) {
  if(newInventoryClassId == null) {
    this.inventoryClassId = new String[0];
  } else {
   this.inventoryClassId = Arrays.copyOf(newInventoryClassId, newInventoryClassId.length);
  }
}
