Camel 2.11.0 release (currently in progress)

New and Noteworthy

Welcome to the 2.11.0 release with approximately XXX issues resolved - including new features, improvements, and bug fixes, such as:

• Added support for SOAP 1.2 in SOAP data format.
• Cache operation for add/update now supports expiry headers to control time to live/idle/eternal.
• Added allowNullBody option to JMS to configure whether sending messages with no body is allowed.
• Added connectOnStartup option to HDFS to allow to connect on demand, to avoid having Hadoop block for long time connecting to the HDFS cluster, as it has a hardcoded 15 minute retry mechanism.
• Added support for daily and weekly trends to Twitter component.
• The Camel Maven Archetypes now generates projects without any license headers.
• Added 'rejectOld' option to the Resequencer to prevent out of order messages from being delivered after capacity/timeout events occur
• Further optimized XPath under concurrent load, and as well ensured resources are cleaned up eagerly
• Added options allowNullBody and readLockMinLength to the File and FTP components.
• Made changed read lock strategy on FTP go faster (eg when the FTP server has a lot of files in the directory) if you enable the fastExistsCheck=true option as well. Notice that some FTP server may not support this.
• HL7 moves the HAPI 2.0 and supports Parser instance into unmarshal and "Terser" language and expression to be able to extract fields from a parsed message. HL7 also upgraded to now use Apache Mina 2.x.
• Add an option HttpMethodRestrict to restrict HTTP method in Jetty and SERVLET
• Add support for selection of Direct-VM consumers by using ant-like path expression.
• The POJO Producing, and POJO Consuming with @Consume, @Produce, @EndpointInject now supports a new {{property} attribute to get the endpoint configuration from a bean property (eg using a getter method); this allows you to configure this on the bean using conventional bean configuration.
• Testing with camel-test-blueprint on Windows no longer tries to cleanup after testing taking up 5 seconds and logging WARNs.
• The File, and FTP components now support fileExist=Move option to move any existing files before writing a file.
• Added option loadStatisticsEnabled on Camel JMX to allow to disable load statistics if not needed (avoids a background thread being in use, to calculate the load stats).
• Enabled "lazy connections" for XMPP providers via the testConnectionOnStartup option
• Added a connection monitor to detect and fix dropped XMPP consumer connections at configurable connectionPollDelay intervals
• Added an ExchangeBuilder to build the exchange in a fluent way.

Fixed issues

• Fixed RoutePolicy used from Spring XML with routePolicyRef may not invoke all callbacks on the policy.
• Fixed MINA consumer to force disconnect upon timeout when doing request/reply, as late replies may cause side effects otherwise.
• Fixed Simple language with empty quoted literals in predicates, so you can compare against empty strings.
• Fixed SOAP data format to set SOAP 1.1 namespace when marhsalling faults.
• Fixed SEDA producer to send to the right BlockingQueue being attached on the SEDA endpoint so that the sent messages don't get lost.
• Fixed using sendEmptyMessageWhenIdle=true on a batch consumer such as File now working with Aggregate EIP when using completionFromBatchConsumer
• Fixed MockEndpoint.expectedBodiesReceivedInAnyOrder to allow asserting on multiple arrival of the same/equal bodies.
• Fixed MyBatis to demarcate the running transactions properly while reading/writing from/to database.
• Fixed Jetty, HTTP, HTTP4, and AHC http components not working in bridge mode if content path have spaces
• Fixed the CXF fallback convertor issue which camel will unregister it when the converter return null.
• Fixed the issue that File2 endpoints on windows without volume name in the path url.
• Fixed the issue of unmarshaling pgp messages encrypted with ElGamal.
• Fixed random Load Balancer to be even spread (before was a little less likely to pick the 1st)
• Fixed Timer to not fire during starting CamelContext
• Fixed XMLSecurity DataFormat to enable retrieval of password-protected private keys for asymmetric decryption

New Enterprise Integration Patterns

New Camel Karaf Command

New Components

• camel-couchdb - for integration with Apache CouchDB
• camel-elasticsearch - for ElasticSearch integration
• camel-sjms - for "Springless" JMS integration
• [camel-neo4j] - for talking to neo4j server from Camel.

DSL Changes

• Added LoggingErrorHandler fluent builder to Scala DSL.

New Annotations

New Data Formats

New Languages

• VTD-XML - for fast and efficient XPath evaluation/splitting using the VTD-XML Library. camel-vtdxml hosted at Camel Extra

New Examples

New Tutorials

API changes/breaking

• HL7 upgraded to now use Apache Mina 2.x.
• Renamed org.apache.camel.component.hbase.HBaseContats to org.apache.camel.component.hbase.HBaseConstants
• Added getter/setter methods for loadStatisticsEnabled on org.apache.camel.spi.ManagementStrategy

Internal/Non API refactorings that may affect users

• The Camel Test Kit provides a default Properties component out of the box; which mean using addComponent("properties", ...) is no longer needed; instead get the component using getComponent("properties") and configure the component instead.

Known Issues

• The Tracer may not output all details for some situations, such as when using onCompletion or intercept, etc.
• The project cannot fully build the site using Maven (e.g. running "mvn site"). There is no plan to fix this, as the project does not use maven site.
• JBoss 7 may log a WARNing when running Camel as a WAR file.

Dependency Upgrades

• Async Http Client 1.7.5 to 1.7.6
• Axiom 1.2.10 to 1.2.12
• BeanIO 2.0.0 to 2.0.1
• ConcurrentLinkedHashMap 1.2 to 1.3.1
• Ehcache bundle 2.5.1_1 to 2.5.2_1
• Groovy 1.8.6 to 1.8.7
• Hazelcast 2.0.2 to 2.3
• HTTP Client 4.1.3 to 4.2.1
• Jettison 1.3.1 to 1.3.2
• Lucene 3.6.0 to 3.6.1
• Netty 3.5.1 to 3.5.5
• Ognl bundle 3.0.4_1 to 3.0.5_1
• Restlet 2.0.14 to 2.0.15
• Saxon 9.3.0.11 to 9.4.0.1
• Spring Framework 3.1.1 to 3.1.2
• Spring Integration 2.1.2 to 2.1.3
• SSHD 0.6.0 to 0.7.0
• Woodstox 4.1.2 to 4.1.3

Important changes to consider when upgrading

• camel-mina2 now uses OrderedThreadPoolExecutor by default. There is a new option orderedThreadPoolExecutor you can configure it to false to revert back to unordered if needed. Mina that using SSL etc. requires ordered.
• The default value of delay option on Timer has been changed from 0 to 1000

Notice

• Maven 3.0.2 or better is required to build the Source
• If you want to deploy Apache Camel 2.11.0 into Apache Karaf, we highly recommend to use the 'jre.properties.cxf' configuration, which is part of Apache Karaf 2.2.5 onwards. For example camel-cxf, camel-mail, and camel-spring-ws requires this to be installable; as well other features may as well.
