---------------------------------------------

Hello, I am experiencing this issue too, 
In particular, it happens to me it fails {code:java} VolatileComponentStatusRepositoryTest.testFilterDatesUsingStartFilter() {code} with:

{panel:title=Error log}
[ERROR] Failures: 
[ERROR]   VolatileComponentStatusRepositoryTest.testFilterDatesUsingStartFilter:132 expected:<Thu Jan 01 00:00:00 CET 1970> but was:<Thu Jan 01 01:00:00 CET 1970>

> Unit test {{VolatileComponentStatusRepositoryTest.testFilterDatesUsingPreferredDataPoints}} may fail with the following:
> {code:java}
> java.lang.AssertionError: 
> Expected :Thu Jan 01 00:00:00 CET 1970
> Actual   :Thu Jan 01 01:00:00 CET 1970
> {code}
> The test creates a {{VolatileComponentStatusRepository}} instance and adds {{java.util.Date}} objects to it starting from epoch (via {{new Date(0)}}).
>  This first date at epoch is the _Actual_ in the _AssertionError_.
> Then filters this list by looking for those that are earlier or matching a _start_ paramater. This _start_ is created from a {{LocalDateTime}} at the default system time zone.
>  This is the _Expected_ in the _AssertionError_.
> In general the issue is the difference in how the list is created (dates that are 00:00:00 GMT) and how the filter parameter date is created (00:00:00 at system time zone).
