Hi! Thanks dracic and Andrea for all hints, I finally solved the problem.
It was the PostGIS version 2.1.7 that caused the error. Obviously in this version the simplification collapsed small lines to points; https://trac.osgeo.org/postgis/ticket/2093#comment:32 might be the bugfix. After updating to 2.2.2 all works fine.

I have some lines imported to postgres by osmosis and rendering the data with the default line style as wms in geoserver 2.7.1.1 fails for scales more zoomed out than 1:70K (though working zoomed more in), failing with the following message: org.geotools.data.DataSourceException: An exception occurred while parsing WKB data An exception occurred while parsing WKB data Invalid number of points in LineString (found 1 - must be 0 or >= 2) WFS shows all data (just 3502 geometries) though. I had a look at the PostgreSQL 9.4.5 database with postgis 2.1.7: ST_IsValid returns true for all linestrings; also is the number of points for all lines >= 2 and the minimum length of all lines is 1.04m ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Geoserver-users mailing list Geoserver-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/geoserver-users
