Multiple constructor-arg with same index=0 withing the same bean element does not throw exception [SPR-6329]

[spring-projects-issues]

shine paul opened SPR-6329 and commented

I have a custom class MyClass

class MyClass {
String string = null;
int count = 0;
public Class(String string){
this.string = string;
}
public class MyString(String string, int count) {
this.string = string;
this.count = count;
}

In my applicationContext.xml
I have something like this

<bean id="MyClassClient" class="MyClass">
<constructor-arg index="0" value="testMe" />
<constructor-arg index="0" value=4 />
</bean>

I have typed the second index=0 by mistake (It should have been 1, so that spring could create the object with two arguments)
However Spring silently ignores my mistake and
creates an instance of MyClass which only takes String as the argument.

I would rather like Spring to complain about my mistake at this point.

Thanks for spotting this! Fixed in 3.0 RC2: reporting such an ambiguity as an error now.
