Weakness Name
Comparison of Object References Instead of Object Contents
Description
The product compares object references instead of the contents of the objects themselves, preventing it from detecting equivalent objects.
For example, in Java, comparing objects using == usually produces deceptive results, since the == operator compares object references rather than values; often, this means that using == for strings is actually comparing the strings' references, not their values.
Common Consequences
Scope: Other
Impact: Varies by Context
Notes: This weakness can lead to erroneous results that can cause unexpected application behaviors.
