Camel EHCache: ClassNotFoundException when persistent cache is initialized

Issue

• My bundle creates a persistent user cache (using ehcache). But when i deploy the bundle to fuse-karaf-container i get a strange behaviour when the perstistent cache ist already filled with some data.
• At deployment time everything seems working fine. The bundle ist started and the cache ist filled with some data. When restart the fuse-karaf-container i get a ClassNotFoundException when the Cache is filled from the persistent data.
• When i stop the fuse-karaf-container, delete the persistent cache directory and start the container again, the cache is correctly filled with data again.
