I know that I can draw quads using

bufferbuilder.begin(GL11.GL_QUADS, DefaultVertexFormats.POSITION_TEX_NORMAL);

Can I use GL11.GL_POLYGON to draw polygons, or is there another GL mode that works? 

Ok nevermind, GL_POLYGON works, I just did it wrong previously

Be aware that the BufferBuilder is designed to uploads quads and assumes quads as the drawing primitive at some of it's methods.

The methods for providing vertex data are safe to use ofcourse, but most of putX aren't.
