Anyone knows how to use JStackAlloc with Eclipse?

I#m currently trying to find out a way to use this:,18843.0.html

with eclipse for my jme project, because i think it will greatly help me to reduce objectcreation/gc, however it always complains about "java.lang.Error: not instrumented". I gues this has someting to do with ant scripts or so, but I miss specific knowledge :frowning:
