Invocation SecuredIdentityManager.lookupById(Class<C> attributedType, String id) results in infinite loop and stack overflow because the decorator is not invoked. Looks like a typo:

Here's the code:

@Override
public <C extends IdentityType> C lookupById(Class<C> attributedType, String id) throws IdentityManagementException

That can't be right. I assume it should be this:

@Override
public <C extends IdentityType> C lookupById(Class<C> attributedType, String id) throws IdentityManagementException

This is a problem since the old lookupIdentityById is deprecated apparently.
