It is true, that static methods can't be overridden in a subclass, however they can be hidden. So final keyword prevents method hiding.
That's correct. However StringEscapeUtils is an utils class with only static methods and is not meant to be subclassed (I wonder why it isn't final btw), so the final modifier is useless.
Finally, the final keyword can slightly improve performance because the JVM should not check if the method is hidden or overridden in a subclass.
There is no polymorphism for static methods, the compiler resolves the static method call depending on the type of the instance, and the bytecode generated has an invokestatic instruction pointing directly to the right method, unlike invokevirtual instructions. There is no runtime impact.
