Fuse ESB Enterprise 7.1.0.fuse-047 uses Apache Camel 2.10. Since the last release, Apache Camel has been upgraded from version 2.9 to version 2.10. This introduces a few migration issues.

The most important change in Apache Camel 2.10 is that Apache Camel now supports Java 7 (JDK 1.7).

You should also note the following important changes:

In Apache Camel 2.10, some components have had their third party dependencies upgraded. See Product Dependencies for details.

In Apache Camel 2.10, the following changes have been made to the Java API:

In Apache Camel 2.10, you need to consider the following component updates:

The simple language no longer trims white space surrounding an expression in the Java DSL. On the other hand, the simple language does trims white space surrounding an expression in the XML DSL by default, but you can disable this behavior by setting trim="false" in the simple element.

In this release, the convertBodyTo DSL command does not propagate the character set as an exchange property when the charset option is set (in previous releases, the character set was propagated in the Exchange.CHARSET_NAME property).

URI normalization now recognizes pre-existing %nn decimal encodings in URI strings.

When using Apache Camel interceptors, the behavior when combining the skipSendToOriginalEndpoint() clause with the when() predicate has changed in Apache Camel 2.10.

Now, when you combine the skipSendToOriginalEndpoint() clause with a when() predicate, the original endpoint is skipped, only if the when() predicate evaluates to true. For example, in the following route, the mock:result endpoint will be skipped, only if the message body is equal to Hello World:

interceptSendToEndpoint("mock:foo")
    .skipSendToOriginalEndpoint()
    .when(body().isEqualTo("Hello World"))
    .to("mock:detour").transform(constant("Bye World"));

from("direct:second")
    .to("mock:bar")
    .to("mock:foo")
    .to("mock:result");

In previous versions, the original endpoint would have been skipped, even if the when() predicate evaluated to false.

The default pattern for thread names is now:

Camel (#camelId#) thread ##counter# - #name#

In previous releases the thread name pattern was:

Camel (${camelId}) thread #${counter} - ${name}

The pollEnrich DSL command now blocks, if no messages are available and no timeout has been configured.

The setting lazyLoadTypeConverter=true is now deprecated and will be removed in a future release. The recommended practice is to load type converters at start up time.

The Apache Camel test kit no longer lazily loads type converters.

Apache Camel now fails faster during type conversion, by throwing TypeConversionException to the caller.

Apache Camel no longer supports using java.beans.PropertyEditor for type conversion. This approach is slow, not thread safe, and uses third party JARs on the classpath, which can cause unwanted side effects.

The keys for MDC logging are now prefixed with .camel.

It is no longer possible to change the destination of the wire tap enterprise integration pattern from JMX.
