Apache Camel CXF

Camel config worked fine with v 2.13.4. After upgrading to v 2.15.1, I get the following error:

Caused by: org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.apache.camel.component.cxf.spring.NamespaceHandler] for namespace [http://camel.apache.org/schema/cxf]: problem with handler class file or dependent class; nested exception is java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/apache/camel/component/cxf/spring/NamespaceHandler, offset=6

In camel configuration I use the following schemes:

    <beans xmlns="http://www.springframework.org/schema/beans"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/cxf"
            xsi:schemaLocation="
