Osmosis issue : Pipeline entities are not sorted

Hi all

I'm using the following cli to create a diff file with osmosis :

osmosis --rri workingDirectory=$dir --simc --wxc $diff_file

It works globally fine, but sometimes failed with the following error message : SEVERE: Thread for task 1-rri failed org.openstreetmap.osmosis.core.OsmosisRuntimeException: Pipeline entities are not sorted, previous entity type=Node, id=3976375557, version=1 current entity type=Node, id=3976375557, version=1.

In that case, removing --simc option seems to work fine and generate a correct osc file but it contains several changes for the same id (which is expected because of removing simplify-changes option !). I had a look at the generated file and it seems --simc option is failing when an id is created and deleted in the same osc file compilation (from 2016-01-28 to 2016-02-01 in my case) :

<create> ... <node id="3976375557" version="1" timestamp="2016-01-29T17:16:56Z" uid="3577326" user="Alain 9-0" changeset="36883598" lat="47.5435886" lon="6.8328761"/> </create> <delete> <node id="3976375557" version="1" timestamp="2016-01-31T05:04:40Z" uid="3577326" user="Alain 9-0" changeset="36883598" lat="47.5435886" lon="6.8328761"/> </delete>

Any idea on how to keep --simc option in any case ?

Thanks a lot for any help

Kind regards,

David
