Override hybrid commonI18NService roundCurrency method

Trying to override spring bean

with Alias

.

I want to pass the roundCurrency

methodcommonI18NService

Definition of OOTB

<alias alias="commonI18NService" name="defaultCommonI18NService"/>
<bean id="defaultCommonI18NService" class="de.hybris.platform.servicelayer.i18n.impl.DefaultCommonI18NService"  parent="abstractBusinessService">
    <property name="languageDao" ref="languageDao"/>
    <property name="currencyDao" ref="currencyDao"/>
    <property name="countryDao" ref="countryDao"/>
    <property name="regionDao" ref="regionDao"/>
    <property name="conversionStrategy" ref="conversionStrategy"/>
</bean>

      

        
        
        
      

    

Our custom code: -

public class DefaultCustomCommonI18NService extends DefaultCommonI18NService
{

    @Override
    public double roundCurrency(double value, int digits)
    {
      // custom logic
        return value;
    }
} 

      

        
        
        
      

    

Inject custom bean: -

<alias alias="commonI18NService" name="defaultCustomCommonI18NService"/>
<bean id="defaultCustomCommonI18NService" class="com.extended.service.impl.DefaultCustomCommonI18NService"  parent="defaultCommonI18NService"/>

      

        
        
        
      

    

But it throws an exception on startUP server
