I'm trying to define a map bean with Spring 3.2.4 with an Enum as the key type, this way:

<util:map id="myMapping" key-type="com.acme.MyEnum">
    <entry key="ENUM1" value="value1" />
    <entry key="ENUM2" value="value2" />
</util:map>

The MyEnum class is a trivial class:

public enum MyEnum
{
    ENUM1,
    ENUM2
}

When creating the application context, Spring throws this exception:

org.springframework.beans.factory.BeanCreationException:

  Error creating bean with name 'myMapping':

    Error converting typed String value for bean property 'sourceMap';
    nested exception is org.springframework.beans.ConversionNotSupportedException:

    Failed to convert value of type 'java.lang.String' to required type
    'com.acme.MyEnum'; nested exception is java.lang.IllegalStateException:

      Cannot convert value of type [java.lang.String] to required type 
      [com.acme.MyEnum]: no matching editors or conversion strategy found

(formatted for better readbility)

I expected Spring to convert the String "ENUM1" to "MyEmum.ENUM1", because of the given key type

key-type="com.acme.MyEnum"

in the mapping bean declaration.

I know how to solve this by doing an alternate bean definition, using <entry>, using the full qualified class name of the enum etc... But I would like to build the defintion as described for easy readability.

Is this a known bug or a lack of understanding on my side?

Thanks a lot for your help!
