Camel 2.18.0 release (currently in progress)

New and Noteworthy

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

• Improved the Bean component to better match method parameter types when using Simple language as parameter values.
• Added BindyConverter that allows to implement custom data converters for Bindy
• The access in the Rest DSL has been deprecated and no longer in use - its not part of swagger specification anymore.
• Camel-NATS now uses JNATS client instead of the deprecated Java_nats one.
• During startup of CamelContext the services that are used as part of routes are now deferred being started to the end of the startup process. Some IoC frameworks like Spring can otherwise causes a circular dependency issue if services are started too early. A side effect is that if service startup failures happen when being started later, they are now wrapped in the FailedToStartupRouteException to better pin point which route thas the problem.
• Improved the startup sequence of Spring Java Config to be similar to Spring Boot that helps prevent Spring initialization errors about circular dependencies issues.
• Added PATCH to Rest DSL
• Added "ends with" operator to the simple language.
• Added BeanIOSplitter to BeanIO that can be used with the Splitter EIP to split big payloads in streaming mode without reading the entire content into memory.

Fixed these issues

• Fixed Bean component to avoid ambiguous error for classes that extends generic interface and calling which could lead to falsly duplicate methods (due Java type erasure inserts bridge methods) 
• Fixed splitting using tarfile could cause OOME if splitting big files which was mistakenly loaded into memory. Now we work on the tar stream directly.
• Fixed Netty HTTP and Netty4 HTTP issue when not specifing a port number then port 80 would not be used but an error about port -1 is not allowed.
• Fixed Swagger Java when using property placeholders in Rest DSL could cause invalid parameters to be included that was from the placeholder.
• The threads EIP now lets Error handling in Camel perform redeliveries if the thread pool would otherwise reject accepting the task. This allows the error handler to perform redeliveries to attempt to put the task on the thread pool queue, or eventually move the message to a dead letter queue etc.
• Fixed Rest DSL adding empty header if specifying a non required query parameter that has no defualt value assigned.

Important changes to consider when upgrading

  (only spring-dm using spring 3.2.x as part of camel-spring in osgi/karaf is still in use - but spring-dm is deprecated and we recommend using blueprint)
