------------------------------------
Dmytro
Do you mind creating a new patch with the updated code from the 1.x branch
which uses your thread safe producer.
Then it would be much easier for me to commit it to the 1.x codebase.
Then we have a solution with concurrent mina producers for both 1.x and 2.0
Backporting the pooling is *way* to much work.

> Key: CAMEL-2049
> URL: https://issues.apache.org/activemq/browse/CAMEL-2049
> Project: Apache Camel
> Issue Type: Bug
> Components: camel-mina
> Affects Versions: 1.6.0
> Environment: Windows XP
> Reporter: Dmytro Rud
> Assignee: Claus Ibsen
> Fix For: 1.6.2, 2.0.0
>
> Attachments: MinaComponent.patch, MinaSocketProducer.java
>
>
> A sample scenario where both MINA producer(s) and consumer(s) are used in the
> same route (e.g. some kind of dispatching or proxying):
> from("mina:tcp://localhost:8888?lazySessionCreation=true&sync=true")
> .to("mina:tcp://localhost:7777?lazySessionCreation=true&sync=true");
> from("mina:tcp://localhost:7777?lazySessionCreation=true&sync=true")
> .process(/*prepare answer*/);
> Due to improper configuration of MINA acceptor and connector instances in
> MinaComponent#createSocketEndpoint(), no more than 15 incoming threads can be
> served at port 8888 -- the producer becomes unable to open an outgoing
> session. This is actually an issue of MINA, not of Camel -- a test
> application written using "raw" MINA shows the same behaviour.
> A solution is to apply configuration rules described, e.g., at
> http://mina.apache.org/configuring-thread-model.html, as done in the attached
> patch.
> Moreover, the standard Camel-MINA producer is not thread-safe -- actually a
> well-known point. A second attached file contains a thread pool-based
> reentrant version, which can be efficiently used for TCP endpoints with both
> parameters 'lazySessionCreation' and 'sync' set to true.
