Hi Dale,
For some reason the [log4j-core
dependencies|http://logging.apache.org/log4j/2.x/log4j-core/dependency-management.html]
page mentions jackson-module-jaxb-annotations 2.4.1 but not
jackson-annotations-2.4.1.
Neither is explicitly included in the pom.xml for the log4j-core module. Not
sure why Maven noticed the jackson-module-jaxb-annotations as a transitive
dependency but not jackson-annotations.
You can probably get the jar you need here:
http://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-annotations/2.4.1

Hi Dale,
this [dependency
page|http://logging.apache.org/log4j/2.x/dependency-management.html] also lists
jackson-mapper-asl 1.9.13 as a dependency. UPDATE: no, sorry, looks like that
is only used by log4j-flume...
Update - I just saw that you've already got the jackson dependencies mentioned
in the dependency management [page for
log4j-core|http://logging.apache.org/log4j/2.x/log4j-core/dependency-management.html],
including jackson-module-jaxb-annotations 2.4.1.
You may another annotations jar (not JAXB), called
jackson-annotations-2.4.1.jar?

> Hello--first time report please bear with me.
> Upgrading project from 2.0-rc1 to 2.0, ran into the following issue:
> Layout<? extends Serializable> xmlLayout = xmlLayout.createDefaultLayout();
> produces the following error:
> Exception in thread "main" java.lang.NoClassDefFoundError:
> com/fasterxml/jackson/core/JsonProcessingException
> I've included the API and Core JAR's to the project path, as previously. For
> reference, I'm comparing this line with the following line that runs
> correctly in rc1:
> Layout<? extends Serializable> fileXMLLayout = XMLLayout.createLayout("true",
> "true", null, null, null, null);
