While searching the repositories, I came across the javadoc files and attached them in eclipse and now eclipse names the arguments correctly
Btw, maybe I should file a bug report but just thought I'd mention it.
There seems to be a bug in GLWindow of newt on windows 7 64 bit. If I specify my client area to 800 x 600 and my window is decorated, the opengl view is partially hidden under the decoration (positioned at 0, 0 of the window and not the client area). If decoration is turned off, the opengl view is viewed correctly.
