Description

When calling

javax.jcr.Property jcrProperty = ...
Value[] values = jcrProperty.getValues();

on a weakreference property the following error occurs:

javax.jcr.ValueFormatException: Unknown value type 10

I think the reason is that org.apache.jackrabbit.rmi.value.SerialValueFactory.createValue(Value value, int type) does not support the property type "weakreference".
See http://svn.apache.org/viewvc/jackrabbit/trunk/jackrabbit-jcr-rmi/src/main/java/org/apache/jackrabbit/rmi/value/SerialValueFactory.java?view=markup in line 159.
Just adding the case for PropertyType.WEAKREFERENCE should fix the problem.
