The best guide is currently the demos/ directory in the source
base. There are a lot of demos showing various features of the
library like animation and off-screen rendering. The relatively
recent GLEventListener interface is also demonstrated there.
This is the recommended way of constructing applications at this
point since it provides a framework in which the library can
function "guaranteed correctly" with no chance of
subclassing-induced bugs.

Try upgrading to the latest version (2.8.2). Make sure your app
uses the GLEventListener interface rather than subclassing. I've
checked this with the NVidia demo (demos/NVidia/VertexArrayRange)
as well as the JCanyon demo
( http://java.sun.com/products/jfc/tsc/articles/jcanyon/ ) and
both can handle being resized without locking up the app. (Note
I'm running on Windows; there might be an X11-specific bug.)
