["Michael Dürig (JIRA)" <ji...@apache.org>]

Michael Dürig updated JCR-2461:
-------------------------------

    Attachment: JCR-2461.patch

This patch disables diffing of property states. Items contained in a batch from the server are set to Status#MODIFIED without establishing whether they differ form their cached values. 

I was able to successfully run all tests with the patch applied. However, I'm not sure whether this patch has further, more subtle consequences which I'm not aware of.

> When RepositoryService#getItemInfos() returns a sufficiently large batch for a path, then the second invocation of getItem() below is significantly slower than the first. 
> String path = ...
> Item i = session.getItem(path);
> i.refresh(false); // same for refresh(true)
> session.getItem(path);
> In my test setup RepositoryService#getItemInfos() returns 3946 elements. The first invocation takes approx. 800ms, the second 3000ms.
