Thanks for the fast reply.
I tried wireframes with the newest version of jPCT AE (July 4, 2013).
First thing, I noticed is the changed API. The method has two additional parameters now:
void com.threed.jpct.World.drawWireframe(FrameBuffer buffer, RGBColor color, int size, boolean pointMode)
BTW... the online documentation still points to the old API version.
Nevertheless, I tried to use the method with various combinations of "size" and "pointMode". Unfortunately, an exception was thrown at every try:
FATAL EXCEPTION: GLThread 1579
java.lang.RuntimeException: Not implemented!

Any Idea, why this happens? Will a fix be available soon?
