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...)
- Reduced the API in thread pool management for Camel component developers. 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 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 ajava.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 requirecommons-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 needcamel-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
