Declaration of lists in XSD should return same java implementation

We can declare lists of string with several manner in nuxeo-core.

<xs:simpleType name="stringList1">
<xs:list itemType="xs:string"/>
</xs:simpleType>

<xs:complexType name="stringList2">
<xs:sequence>
<xs:element name="item" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>

But at java level, it returns differents types java.lang.String[] for the first on and java.util.ArrayList for the second. It should return for all: java.util.ArrayList.

A failing test is attached to show the problem.
