"Unknown value type 10" when reading values of a weakreference property via RMI
-------------------------------------------------------------------------------

                 Key: JCR-3260
                 URL: https://issues.apache.org/jira/browse/JCR-3260
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-jcr-rmi
    Affects Versions: 2.4, 2.3.7, 2.2.11, 2.1.6, 2.0.5
            Reporter: Torsten Witte


When calling

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

on a weakreference property the following error occurs:

{noformat}
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.
