> apache/commons-configuration — 7 Cloneable classes missing equals()/hashCode()
> ------------------------------------------------------------------------------
>
> Key: CONFIGURATION-855
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-855
> Project: Commons Configuration
> Issue Type: Bug
> Reporter: Shan Jiang
> Priority: Major
>
> ### Summary
> Seven classes implement `Cloneable` with correct `clone()` but do not override
> `equals()`/`hashCode()`. `x.clone().equals(x)` always returns `false`.
> ### Affected classes
> - `BaseConfiguration`
> - `CombinedConfiguration`
> - `CompositeConfiguration`
> - `BasicBuilderParameters`
> - `FileBasedBuilderParametersImpl`
> - `CombinedBuilderParametersImpl`
> - `MultiFileBuilderParametersImpl`
> ### How this was found
> Detected by an automated JDK conformance oracle
> (`ObjectOracles.checkCloneEqualsConsistency`).
