Why Am I Getting an IllegalStateException While Adding Bcrypt to my Spring-Security.XML file?

Question

I have implemented bCrypt encoding on a small app I am doing. Currently, I can create a user, and encrypt the password. Prior to encryption, I could have the user login with their email address, and a plain text password stored in the DB. Now I am getting a 404 error when I simply run the application out of Eclipse.

The error only started occurring after I added the following line in my spring-security.xml file

        <password-encoder ref="encoder" />  

The error I am seeing in the console is the following.

Caused by: java.lang.IllegalStateException: Cannot convert value of type [org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder] to required type [org.springframework.security.authentication.encoding.PasswordEncoder] for property 'passwordEncoder': no matching editors or conversion strategy found
at org.springframework.beans.TypeConverterDelegate.convertIfNecessary(TypeConverterDelegate.java:231)
at org.springframework.beans.BeanWrapperImpl.convertIfNecessary(BeanWrapperImpl.java:447)

Here is how I have Bcrypt implemented in my XML.

 <authentication-manager alias="authenticationManager">
    <authentication-provider>
    <password-encoder ref="encoder" />  
        <jdbc-user-service data-source-ref="dataSource"
            users-by-username-query="
            SELECT email as username, passwordConfig as password, active as enabled 
            FROM Employee
            WHERE email=?"
            authorities-by-username-query="
            SELECT email as username, role 
            FROM EmployeeLEFT OUTER JOIN Roles 
            ON Employee.RoleID=Roles.roleId 
            WHERE email=?" />
    </authentication-provider>
</authentication-manager>

<beans:bean id="encoder" 
class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder">
<beans:constructor-arg name="strength" value="11" />
