Camel 2.19.0 Release (currently in progress)
New and Noteworthy
Welcome to the 2.19.0 release which approx XXX issues resolved (new features, improvements and bug fixes such as...)
- Returning
null
from Bean should work similar to howsetBody
andtransform
works when they set anull
body. - The Camel Spring Boot starter components now have their auto configuration depends on
org.apache.camel.springboot.CamelAutoConfiguration
which makes it easier writing unit tests where you can excludeorg.apache.camel.springboot.CamelAutoConfiguration
to turn off Camel Spring Boot auto configuration completely. - Camel now supports OWASP dependency check maven plugin
- Camel-Nats component now supports TLS
- Camel-Metrics component now supports Gauge type
- File consumer now supports idempotent-changed and idempotent-rename read lock strategies for clustering.
- Camel Catalog now supports custom runtime providers that only includes the supported Camel components, languages and data formats running in that container. For example for Karaf or Spring Boot in the camel-catalog-provider-karaf and camel-catalog-provider-springboot.
- The bean component will when calling a method that returned an instance of
Callable
now call that callable to obtain the chained result. This allows to call Groovy functions/closures etc. - Failover Load Balancer with inheritErrorHandler=false, now allows Camel's Error Handler to react after the load balancer is exhausted.
Fixed these issues
- Fixed Hystrix EIP to also execute fallback if execution was rejected or short-circuited or other reasons from Hystrix.
- Fixed adding new routes to running CamelContext and if the new routes would fail to startup, then before these routes would "hang around". Now only succesful started routes are added.
- Adding or removing routes that starts from Undertow no longer restart the entire HTTP server
- VM endpoint should prepare exchange with the CamelContext from the consumer and not from cached endpoint which can be different
- Fixed a bug when using Rest DSL with SERVLET could cause a java.io.IOException: Stream closed exception when using Bean in the route.
- Fixed an issue when using
pipeline
in Java DSL not setting up the EIP correctly which could lead to runtime route not as intended. - Fixed Netty douhle buffer release leak in Netty4 and Netty4 HTTP

Known Issues
Important changes to consider when upgrading
- Camel now uses Karaf 4.x API and therefore not possible to run on older Karaf versions
- camel-spring-boot now don't include prototype scoped beans when auto scanning for RouteBuilder instances, which is how camel-spring works. You can turn this back using the includeNonSingletons option.
