> When using JCache-annotations the DefaultCacheKeyGenerator exclusively looks at parameter values to form the cache key. Therefore it will be very likely that collissions occur (resulting in difficult to find ClassCastExceptions). The provided patch uses the method- and class names as additionally values to make the cache key more unique.
> Might also add that I am aware that by spec this should not be an issue when no cachename is given (as it should generate a cache using the class-name), but when a cache name is given collissions may occur.
