addElement(Element element) methods can fail
--------------------------------------------
Key: ECS-1
URL: https://issues.apache.org/jira/browse/ECS-1
Project: ECS
Issue Type: Bug
Environment: in Ibm Virtual Machines, but probabily also in Sun
Virtual Machines
Reporter: Mauro Manfrin
Priority: Critical
The class ConcreteElement exposes a method
addElement(Element element)
that calls
addElementToRegistry(Integer.toString(element.hashCode()),element);
so it gives a key valued element.hashCode() to that element.
That's the point: element.hashCode() can't be a unique key because sometimes we
can have two elements with the same hasocode.
javadoc states:
"It is not required that if two objects are unequal according to the
equals(java.lang.Object) method, then calling the hashCode method on each of
the two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results for
unequal objects may improve the performance of hashtables."
So sometimes, two different objects can have the same hashCode!
So, sometimes two calls to addElement(element) can result in only the second
object stored in the ConcreteElement.
So sometimes, on out instalaltion some table rows misses, or some row cells
misses or...
