Session ). |

If any Exception occurs when executing the provided lambda, then the transactions should be rolled
back - but if it is the declared special MatsEndpoint.MatsRefuseMessageException
, then the implementation should
also try to ensure that the underlying JMS Message is not redelivered (no more retries), but instead put on
the DLQ right away. (Beware of "sneaky throws": The JVM bytecode doesn't care whether a method declares an
exception or not: It is possible to throw a checked exception form a method that doesn't declare it in
several different ways. Groovy is nasty here (as effectively all Exceptions are unchecked in the Groovy
world), and also google "sneakyThrows" for a way to do it using "pure java" that was invented with
Generics.)
