latformTransactionManager not found in 2.4.0

[Ron Smith]

After moving from camel 2.3.0 to 2.4.0 I am getting the error:

java.lang.ClassNotFoundException:
org.springframework.transaction.PlatformTransactionManager

when I execute:

context.addComponent("myjms",
JmsComponent.jmsComponentAutoAcknowledge(topicConnectionFactory));

I am including every JAR in the lib directory including the optional ones.
This is code that was working in 2.3.0.
