We (will soon) drop Scala 2.9 support for Camel

Apache Camel comes with some amazing DSLs out-of-the-box. The one I like the most is Scala DSL. The reason I like it so much is because I'm Scala enthusiast and because mentioned DSL provides Scala-specific extensions to the Java-based Camel route builder.

If you have ever wondered how would it be to write Camel routes just like this...

"pop3://user@host" process(_.in = "JMS FTW!") to "jms:queue"

...then keep in mind that Scala DSL can do you some favor.

At the beginning of the January Scala 2.10 has been officially released. Since the latest version of my favorite language significantly breaks binary compatibility against Scala 2.9, interesting discussion occurred on the Camel mailing list. The key facts resulting from the latter conversion are as follows.

• Camel 2.11 will provide support for Scala 2.10 via camel-scala module (the one shipping Scala DSL for Camel so far)
• Camel 2.11 will provide support for Scala 2.9 via new camel-scala_2.9 module. The latter module will marked as a deprecated just after its release.
• starting from the Camel 2.12 or 3.0 (whichever comes as the first) we will drop support for Scala 2.9 

If you use Camel and Scala together in the same project, please be prepared that sticking to the Scala 2.9 for a long run might be a problem for you.
