You're right, it's more reasonable to use something not dependent on the IDE, it's more an habit on my side...
An example for this class of what Eclipse would generate :
```    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((credentialClass == null) ? 0 : credentialClass.hashCode());
        result = prime * result + ((id == null) ? 0 : id.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        BasicCredentialMetaData other = (BasicCredentialMetaData) obj;
        if (credentialClass == null) {
            if (other.credentialClass != null)
                return false;
        } else if (!credentialClass.equals(other.credentialClass))
            return false;
        if (id == null) {
            if (other.id != null)
                return false;
        } else if (!id.equals(other.id))
            return false;
        return true;
    }
```
Pretty ugly in fact, but it's easy for lazzy developers : just right click, "generate hash and equals methods"...
If we made a choice, it would make sense to apply it globally for the CAS server (as soon as possible) and add it in the CAS code conventions ?
