How much RAM do you have? What a CPU?
How do you compile? The complete Jar or only needed references? I think 
the problem shouldn't occur if you compile only needed references?
That GCJ needs a lot of RAM is a well known (and unfortunately ignored) 
problem. Try disabling optimization and maybe you also should manually 
increase the swap space of you machine.
