I think you are absolutely correct. I am using -XstartOnFirstThread, but I noticed when the application works it outputs a message about the CocoaCompatibilty enabled. This is triggered somehow from the jogl calls. This indicates there is some threading going on behind the scenes as that compatibility layer is for dealing with asyncronous calls to or from awt threads.
I have decided to dump QT and move to a swing UI. I have read a lot of posts about the upgrades and openGL 2D integration it has in java 1.6 so I guess I will just try it out. I will do most of my rendering to FBO's anyway so I won't be using the pbuffer crap in it now; jogl exposes the base opengl calls and their extensions. QT freezes if you don't use -XstartOnFirstThread in your java arg; this is an indicator that mixing it with anything awt replated (as jogl certainly is) is going to have some perhaps dire consequences. Two of the three hard problems I came across were due to QT; I guess from my perspective, until they port it to cocoa, it isn't really useful for java on the mac. Really rough introduction to java, however. Everything I tried went bang in odd ways; and it wasn't clojure as much as it was jar, jni, dylib, mac hell. Luckily I work in c++ so I am used to all this shit. Thanks for the reply!
