>    Affects Versions: 2.18.1

> The "transacted" configuration requires a Spring environment. We use JavaEE and we needed
to use "transacted". We ported the Spring implementation of the TransactionErrorHandler to
JavaEE.
> There is only one major difference: Spring's TransactionErrorHandler derives from org.apache.camel.processor.RedeliveryErrorHandler
which brings the behavior that redelivery is done within the transaction. In our implementation
there is a RedeliveryErrorHandler which uses the TransactionErrorHandler to force a rollback
and create a new transaction for each redelivery.
> Example usage:
> {noformat}
> errorHandler(transactionErrorHandler() //
>                 .setTransactionPolicy("PROPAGATION_SUPPORTS") //
>                 .maximumRedeliveries(5) //
>                 .maximumRedeliveryDelay(5000) //
>                 .collisionAvoidancePercent(10) //
>                 .backOffMultiplier(1.5));
> from("direct:sample") //
>                 .transacted("PROPAGATION_REQUIRES_NEW")
>                 .to("bean:sampleBean");
> {noformat}
