Aled Sage resolved BROOKLYN-305.
--------------------------------
Resolution: Fixed
Fix Version/s: 0.10.0
> Rebind fails when entity attribute contains special unicode character ""
> ------------------------------------------------------------------------------
>
> Key: BROOKLYN-305
> URL: https://issues.apache.org/jira/browse/BROOKLYN-305
> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.9.0
> Reporter: Aled Sage
> Fix For: 0.10.0
>
>
> I had an entity with a sensor value that contained unicode character 27 (in
> the persisted state, this was converted to by xstream to {{}} and
> written to the xml file).
> On restarting Brooklyn, it failed to restart. This is because {{}} is
> an illegal character in xml. The xstream deserialization works fine, but our
> code first uses xpath to extract the entity id from the raw xml. That fails
> with the exception below:
> {noformat}
