Labeling of polygon borders with follow-line may fail (when rings are small enough)

Description

Using Geoserver 2.12 I experience missing tiles. Digging deeper I found a problem while Geoserver is labeling some geometries. This is our style, which produces the exceptions at the bottom.

Same layer works using Geoserver 2.10 without any problems.

I am on the way to produce a more minimalistic example

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 [geom_type=1]{ mark: url("kontrollobjekte/${schild}"); mark-mime: "image/svg"; mark-size: 60; label: [objekttypname]; font-fill: black;} [geom_type=2]{ stroke: #333333, #6699FF; stroke-width: 5px, 3px; stroke-linecap: round; z-index: 0, 1; label: [objekttypname]; label-offset: 7px; font-fill: #333333;} [geom_type=3]{ fill: #000080; label: [objekttypname]; label-offset: 7px; font-fill: white;}

GeoServer throws the following exception and stops rendering the actual request:
