Camel 2.9.0 release (currently in progress)

New and Noteworthy

Welcome to the 2.9.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)

• Introduced ThreadPoolFactory with a simpler API for 3rd party SPI. See Threading Model for more details.
• Fixed issue with Properties component may cache duplicates and thus take up unnecessary memory in the cache
• Fixed issue with Tracer out exchanges when using Asynchronous Processing by the Asynchronous Routing Engine
• Fixed issue with Components or Endpoints not being registered in JMX when using POJO Producing, POJO Consuming or other Camel bean annotations.
• The SOAP data format now supports using multiple parameters on the JAXB objects.
• The Bean component now supports specifying parameter values to use directly in the method syntax. See more details at Bean Binding. For example to invoke a bean with body as first parameter, and a boolean true as second you can now do: .to("bean:myBean?method=myMethod(body, true)")
• Fixed issue which could cause DefaultUnitOfWork to throw a java.util.EmptyStackException under heavy load
• Improved labels of all model definitions which appear in Tracer output
• Fixed issue with MDC logging not remembering old values, for example when using a ProducerTemplate from within routes to send new messages.
• Reduced dependency for camel-core to not require commons-management JAR anymore
• Added blueprint support of cxfrs endpoint.
• Camel no longer depend on using Spring JARs for having Camel enlisted in JMX.
• Introduced a set of Camel JMX annotations in org.apache.camel.management that can be used to easily instrument Camel Components, EIPs, custom Processors, Beans etc. for being managed in JMX. Using the Spring JMX annotations is still supported (you would need camel-spring on the classpath).
• Fixed issue when invoking a Bean and that bean is using a @Bean in its method signature, causing the @Bean to not invoke its intended method
• Updated the Aggregator2 to allow for manually completing all exchange groups by sending a message containing the header Exchange.AGGREGATION_COMPLETE_ALL_GROUPS set to true.
• Fixed issue with Bindy unmarshalling in key value mode when using @OneToMany bindings, may cause inconsistency for multiple threaded unmarshalling
• Removed dependency on Spring JARs in the following components: Validation, XSLT, Velocity, FreeMarker, Flatpack, StringTemplate, iBATIS, Jing, MSV, XQuery, and Test
• Using pollEnrich with a file/ftp endpoint will now only poll on demand, beforehand the polling could be started when the route started.
• Added option ReplyToType on JMS to allow people to control which kind of reply queue they are using (temporary, shared, exclusive). Added support for exclusive reply queues. Mind they have some limitations, by which the shared dont have. So use exclusive with a bit caution.
• Added wereSentTo to NotifyBuilder allowing to set expectation that Exchanges was sent to the given endpoint uri.
• Bindy in CSV format now uses trim, clip, and length attributes on @DataField when marshalling.
• Improved managed browsable endpoints (JMX) so you can browse all/range messages and whether to include message body or not.
• File and FTP endpoints is now browsable endpoints. For example using JMX people can browse the endpoint listing available files. The returned data does not contain the actual file body to avoid loading big data into memory.
• Added replaceFrom to AdviceWith making it easy to swap a route input endpoint with something else, for easier unit testing.
• Added Java DSL support for route autoStartup(String) and autoStartup(boolean)
