Naming a method hashcode() is either:

• A bug. Overriding Object.hashCode() was meant and the application does not behave as expected.
• Done on purpose. The name however will confuse every other developer, who will think it is a bug.

In both cases, the method should be renamed.

The following code:

public int hashcode() { /* ... */ }    // Non-Compliant

should be refactored into:

@Override
public int hashCode() { /* ... */ }    // Compliant
