>             Project: Jackrabbit

> An ArrayIndexOutOfBoundsException occurs when I am trying to restore a previous version
of a node when it contains empty multi value properties.
> Here is a stack trace for where in he core code the exception is occurring:
> Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 0
> 	at org.apache.jackrabbit.core.NodeImpl.restoreFrozenState(NodeImpl.java:3856)
> 	at org.apache.jackrabbit.core.NodeImpl.internalRestore(NodeImpl.java:3799)
> 	at org.apache.jackrabbit.core.NodeImpl.internalRestore(NodeImpl.java:3760)
> 	at org.apache.jackrabbit.core.NodeImpl.restore(NodeImpl.java:3057)
> ...
> Line 3856 in NodeImpl.restoreFrozenState is:
>                 internalSetProperty(props[i].getName(), prop.getValues()[0]);
> This is always being called even for multivalued properties (the previous "if (prop.isMultiValued())"
is always returning false). Even if I have a value in the multi-value property, only the first
item is restored because the prop.isMultiValued() call in NodeImpl.restoreFrozenState() never
returns true regardless of whether the property is multivalued or not.
> The node definition is:
>   <nodeType name="bob:customType"
>             isMixin="false"
>             hasOrderableChildNodes="false"
>             primaryItemName="">
>     <supertypes>
>       <supertype>mix:lockable</supertype>
>       <supertype>mix:versionable</supertype>
>     </supertypes>
>     <propertyDefinition name="bob:properties"
>                         requiredType="Reference"
>                         autoCreated="false"
>                         mandatory="true"
>                         onParentVersion="COPY"
>                         protected="false"
>                         multiple="true"/>
>   </nodeType>
> A new node is created with the primary type being "bob:customType" and an empty array
of References is set as the value for that property in the node.
