[infinispan-dev] Issue with transaction rollback

[Sanne Grinovero]

Hi Faseela,
you should not attempt to mutate the value retrieved from the Cache.
I would suggest to only store immutable objects in a Cache; in other
words rather than invoking a setter on property Name, replace the
entry with a new instance of Rollback which has the new name.
