GeoGebra

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

GeoGebra

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

@Override

    switch (type) {

Most likely, GL.GL_TRIANGLE_FAN was intended

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