(11:14) <tfr42>https://github.com/deegree/deegree3/issues/1033#issuecomment-590834724
(11:27) <tfr42>I do propose to downgrade to JTS 1.15.0 for now, open an issue to get the Clipper resolved soon and to upgrade to JTS 1.16.1
(11:28) <copierrj>Agreed
(11:28) <stenger>+1

(11:29) <StephanR>And the PR was https://github.com/deegree/deegree3/pull/949
(11:30) <StephanR>+1
(11:32) <tfr42>+1
(11:41) <copierrj>https://github.com/deegree/deegree3/pull/494
(11:44) <copierrj>https://github.com/deegree/deegree3/tree/master/deegree-core/deegree-core-rendering-2d/src/main/java/org/deegree/rendering/r2d/strokes
(11:45) <tfr42>PR to downgrade JTS https://github.com/deegree/deegree3/pull/1045

(11:47) <StephanR>+1
(11:47) <tfr42>+1
(11:47) <tfr42>#1045 is merged
(11:49) <StephanR>A possible approach to correct the clipper would be to adjust the treatment of the orientation of the geometries so that the orientation of the original geometry corresponds to that of the clipped one.
(11:50) <tfr42>I will add the findings about ShapeReader and QGIS unable to reade teh SHAPE files to #1033
(11:52) <tfr42>next topic - current status of CI
(11:53) <tfr42>http://buildserver.deegree.org/view/Pull%20Requests/
(11:54) <tfr42>Thats stil the error: org.apache.maven.surefire.booter.SurefireBooterForkException: ExecutionException The forked VM terminated without properly saying goodbye. VM crash or System.exit called?
