Description

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.
