Is it that it extends vector, so methods from vector might be misused to disturb the stack ?

Exactly. From this URL (http://www.cs.colostate.edu/~rta/publications/Computer00.pdf), we have:

Class java.util.Stack is a subclass of
java.util.Vector. Stack defines common stack methods
such as push(), pop(), and peek(). However, because
Stack is a subclass of Vector, it inherits all the methods
Vector defines. Thus, you can supply a Stack
object wherever the program specifies a Vector object.
A program can insert or delete elements at specified
locations in a Stack object using Vector’s insert-
ElementAt or removeElementAt methods. It can even
use Vector’s removeElement method to remove a specified
element from a Stack object without regard to
the element’s position in the stack.

No, Stack Overflow does not have any concern with this.
That is related to JVM memory.

Java stack is not a proper implementation of actual Stack data structure. A pure stack should allow only push pop and peek. Java stack allows more..

One more flaw is since Stack uses Vector (which in turn use the Array for its implementation) there is no flexibility for using linked list for Stack.
