HashCodeCacheKeyGenerator can't cache bidirectional associations objects

Tow class User and Type:
User:
name:String
type:Type

Type
name:String
users:List<User>

User and Type is bidirectional associations.

a cached method: List getAllUser(Type type)

when caching the method, spring-modules will report StackOverflowError.

Now I'm setting HashCodeCacheKeyGenerator.generateArgumentHashCode to false, running ok.

But I think for bidirectional associations objects, HashCodeCacheKeyGenerator using recursion is not perfection.
