FileIdempotentRepository fileStore does not get loaded on bootrapping, therefore files are processed again

I am using JVM based initialization of Camel using Spring.
I use the documented Camel initialization procedure of main.setApplicationContext("my-spring-camel-config.xml");
main.start()

I also use the documented FileIdempotentRepository that points to a FileStore.
However, when Camel initializes this filestore is not loaded up. Hence, the LRU cache contained within this is empty.
As a result, all my files are FTPed again from the remote server.

This happens everytime I start my JVM resulting in expensive FTP of files.
