Incorrect interpretation of the "expiry".

Java SDK has two kinds of functions. The first functions accepts expiry as CommonDurabilityOptions, the second functions as an simple Duration object.
When I call collection.upsert() with UpsertOptions.upsertOptions().expiry(duration) then for the duration less than 30 days the value is interpreted as an offset and in other case as a absolute time stamp.
But when I call collection.touch() or collection.getAndTouch() with an offset more than 30 days Couchbase immediaely deletes the document.

I have a test for the problem and it demonstrates this odd behaviour.
