camel-spring-amqp failed to run with tomcat 8 + jdk 1.7

[systembugtj]

I have a tomcat 7 + jdk 1.7, but failed to use 1.7.0 version.

java.lang.UnsupportedClassVersionError: amqp/spring/converter/XStreamConverter : Unsupported major.minor version 52.0 (unable to load class amqp.spring.converter.XStreamConverter)

Looks like the latest version is compiled with java 8. Do you mind to make it compatible with jdk 1.7
