>          Components: camel-hazelcast
>    Affects Versions: 2.19.2

> As mentioned in docs 
> http://docs.hazelcast.org/docs/3.8.4/manual/html-single/index.html#creating-a-transaction-interface
> Data structures should be transaction-aware and initialized inside of transaction context. Now hazelcast seda component uses queue initialized externally for the transaction. So when we rollback transaction - things stay the same like we already committed changes (this simply noop).
> Patch should look like (but exactly this version fails tests, so I should investigate more)
> {code:none}
