Rajat Khandelwal commented on LENS-930:
---------------------------------------
I went through the code and DateUtil is not involved in this path. There's a
DateFactory which keeps dates cached. This cache is a two-level hash map
Map<UpdatePeriod, Map<Integer, Date>>, with a lazy computation of Date values
in the inner map. On first access of any <updatePeriod, offset> value, entry of
<updatePeriod, 0> is ensured and <updatePeriod, offset> is returned from cache
or calculated if required. This test case is hitting <DAILY, 0>, <DAILY, -1>
and <DAILY, -2>, which are supposed to be already present because of the static
initializer in DateFactory class.
The failure is in a between clause and the clause is <between 2 days back and
today>. Today is supposed to be at <DAILY, 0>, which seems unlikely to go wrong
because the scenario with <DAILY,0> being wrong but <DAILY,-2> being correct
isn't plausible since the latter is calculated based on the value of the
former.
Unsure of how to reproduce and debug this further. Will update if I think of
something. Suggestions are welcome.
