Validation of constructor-arg 'type' attribute

Is there any validation on the type attribute of a bean's contructor argument? I think that there should be and an exception should be raised when the target 'type' cannot be converted from the value/ref of the object specified.

Code:

---

<bean class="java.net.InetSocketAddress">
    <constructor-arg value="fred" type="String" />
    <constructor-arg value="bob" type="int" />
</bean>

---

Using Spring 3.1.0 in practice, fred and bob are parameterised with ${} and should have been injected at runtime. The error below is produced and based this, I tried to resolve an issue that didn't exist.

Code:
