Camel 2.20.0 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...)

• The Camel Maven Plugin can now validate for duplicate route ids in your source code.
• Splitted Twitter component into 4, now directmessage, seach, streaming and timeline has its own endpoint and scheme. See documentation for more details
• Introduced HeadersMapFactory SPI which allows to plugin different implementations, or to use case sensitive maps that are faster than the default.

Fixed these issues

• Fixed a infinitive recursion in Camel's Error Handler when an onException was routing to another route using direct endpoint and this route would throw a new exception that would circle back to the same onException or at a later point, which will cause an endless recursion.
• Fixed a potential issue with masking password from URI using RAW(xxx) would reveal part of the password if the password contains a & character.
• The Restlet component is now internally using curly brackets for its uri patterns instead of regular parentheses so it works similar to the other REST component and as Restlet framework itself does
• Fixed Hystrix EIP having wrong default for circuitBreakerForceClose when using camel-hystrix-starter with Spring Boot. The default should be false and not true
• Fixed Hystrix EIP when failing and running fallback not signaling to Hystrix itself so it can keep state of the failure and react accordingly to run in half-open mode as well.
• Fixed MDC logging loosing route id after calling a direct route from within a transacted route
• Fixed a regression with Bean and Simple OGNL expressions causing ambiguous method call exception when calling method implemented by super class when method is defined by interface and abstract class
• Fixed Rest DSL (server side) not returning response on all valid uri paths when clients call using a HTTP OPTIONS request
• Fixed Rest producer not using HTTP method (verb such as PUT) from the endpoint uri when calling a remote REST service

Important changes to consider when upgrading

• Maven 3.3.3 or newer is required to build the project

• camel-infinispan - the result is not more set in the CamelInfinispanOperationResult header but in the in body. To change this behavior you can set the header CamelInfinispanOperationResultHeader with the name of the header that should contains the result or with the resultHeader uri option

• camel-infinispan - the uri option command has been deprecated and replaced by operation for consistency
• camel-infinispan - the commands are now int the short form PUT, GET etc. old operation names like CamelInfinispanOperationPut, CamelInfinispanOperationGet etc have been deprecated.
• camel-undertow - matchOnUriPrefix option is defaulted to be FALSE in order to make it consistent with other components like Camel HTTP components.
• Splitted Twitter component into 4, now directmessage, seach, streaming and timeline has its own endpoint and scheme. See documentation for more details
