[jira] [Created] (BROOKLYN-102) Rebind fails for MongoDB
Aled Sage created BROOKLYN-102:
----------------------------------
Summary: Rebind fails for MongoDB
Key: BROOKLYN-102
URL: https://issues.apache.org/jira/browse/BROOKLYN-102
Project: Brooklyn
Issue Type: Bug
Affects Versions: 0.7.0-SNAPSHOT
Reporter: Aled Sage
I deployed an app with a single MongoDB server, running with `brooklyn launch --persist auto`. I then stopped Brooklyn, and restarted it. It failed to rebind to the MongoDB entity's persisted state with the error shown below:
```
2014-12-09 21:37:36,835 WARN Error deserializing memento (attempt 1 of 5): com.thoughtworks.xstream.converters.ConversionException: No field 'loadFactor' found in class 'com.mongodb.CommandResult' : No field 'loadFactor' found in class 'com.mongodb.CommandResult'
---- Debugging information ----

version : 0.7.0-SNAPSHOT
```
This is easily reproduced in an integration test - just wait for the sensor `MongoDBServer.STATUS_BSON` to be populated before rebinding.
