New Revision: 1238463
URL: http://svn.apache.org/viewvc?rev=1238463&view=rev
Log:
CAMEL-4961: Added isTransactedRedelivered to Exchange, which allows to better
track redelivered messages, from ex JMS brokers. Makes easier to correlate in
logs and whatnot. Improved TX logging in TransactedErrorHandler. Polished the
scala RichExchange as well, as slight API change in Exchange.
Added:
