Apache Dubbo

V6067 Two or more case-branches perform the same actions. JVMUtil.java(67), JVMUtil.java(71)

GeoGebra

V6067 Two or more case-branches perform the same actions. PointNDFold.java(38), PointNDFold.java(43)

private static GeoElement doGetTemplate(
        Construction cons,

GeoGebra

V6067 Two or more case-branches perform the same actions. RendererImplShadersD.java(243), RendererImplShadersD.java(245)

@Override
protected int getGLType(Type type) {
    switch (type) {
    case TRIANGLE_STRIP:
        return GL.GL_TRIANGLE_STRIP;
    case TRIANGLE_FAN:

    case TRIANGLES:

        return GL.GL_LINE_LOOP;
    case LINE_STRIP:
        return GL.GL_LINE_STRIP;

    return 0;
}

Most likely, GL.GL_TRIANGLE_FAN was intended

GeoGebra

V6067 Two or more case-branches perform the same actions. DrawConic3D.java(212), DrawConic3D.java(215)

@Override

          createTmpCoordsIfNeeded();
          brush.segment(tmpCoords1.setAdd3(m, tmpCoords1.setMul3(d, minmax[0])),
              tmpCoords2.setAdd3(m, tmpCoords2.setMul3(d, minmax[1])));
          break;

        case GeoConicNDConstants.CONIC_PARALLEL_LINES:
          updateLines(brush);
          break;
        default:
          break;
      }
    }
  }
}

The class has updateCircle method which most likely was intended to be utilized here
