Question

How can I find out if a certain HibernateProxy is in the first level cache?

The code is roughly

for (HibernateObject obj : objects) {
    if (HibernateUtils.isHibernateProxyInCache(
        obj.getExpensiveLazyObject())
    ) {
        display(obj.getExpensiveLazyObject());
    } else {
        display("click here to see expensive lazy object");
    }
}

the code I need is HibernateUtils.isHibernateProxyInCache, but I don’t know how to implement it.

I think you’re looking for Hibernate.isPropertyInitialized.

Calling HibernateUtils.isHibernateProxyInCache(obj.getExpensiveLazyObject()) would initialize the proxy to the expensive lazy object, so your method would always return true.
