[java] CloneMethodMustImplementCloneable triggers for interfaces · Issue #1005 · pmd/pmd · GitHub

Affects PMD Version:
6.2.0

Rule:
category/java/errorprone.xml/CloneMethodMustImplementCloneable

Description:
The code below did not trigger this rule before PMD 6.2.0.

The clone() method is defined in the interface so the return value is of type Foo instead of Object.

Code Sample demonstrating the issue:

public interface Foo
    extends Serializable, Cloneable {
    Foo clone() throws CloneNotSupportedException;
}

Running PMD through: Gradle
