spring redis wrong result

I am using Spring Redis with the @Cacheable annotiation for two methods. When I call one method I am getting a result cached for the other method.

How can it happen that I get the result from the wrong cache while I configured a different cache for each method using the @Cachebale annotation?

Setup: Spring Version 4.1.6. Redis data 1.5 and Redis client 2.7.0.

Example code:

@Cacheable("test1")
    public List<String> findSgsns() {
}

@Cacheable("test2")
    public List<String> findSgsns2() {
}
