Aled Sage created BROOKLYN-305:
----------------------------------
Summary: 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
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}
The workaround is to replace this character in the persisted state (after first
backing it up, obviously!):
{noformat}
tar czf persisted-state.tgz persisted-state/
cd persisted-state/
find . -type f -exec sed -i.bak 's//X/g' {} \;
{noformat}
