I am experiancing weird error. While I type or do any stuff in my current project this error dialogue box appears frequently
.
Could you try to download another build of Katalon and reinstall it?
The exaception thrown to indicate that your code has attempted to cast an object to a subclass of which it is not an instance. This means that ClassCastException occurs when you try to cast an instance of an Object to a type that it is not. Type Casting only works when the casted object follows an is a relationship to the type you are trying to cast to.
It is good practice to guard any explicit casts with an instanceof check first:
if (myApple instanceof Fruit) {
Fruit myFruit = (Fruit)myApple;
}
When will be ClassCastException is thrown:
-
When you try to cast an object of Parent class to its Child class type, this exception will be thrown.
-
When you try to cast an object of one class into another class type that has not extended the other class or they don’t have any relationship between them.
